Bluetooth: Fix ACL alive for long in case of non pariable devices

For certain devices (ex: HID mouse), support for authentication,
pairing and bonding is optional. For such devices, the ACL alive
for too long after the L2CAP disconnection.

To avoid the ACL alive for too long after L2CAP disconnection, reset the
ACL disconnect timeout back to HCI_DISCONN_TIMEOUT during L2CAP connect.

While merging the commit id:a9ea3ed9b71cc3271dd59e76f65748adcaa76422
this issue might have introduced.

netfilter: ipset: Consistent userspace testing with nomatch flag

The "nomatch" commandline flag should invert the matching at testing,
similarly to the --return-nomatch flag of the "set" match of iptables.
Until now it worked with the elements with "nomatch" flag only. From
now on it works with elements without the flag too, i.e:

 # ipset n test hash:net
 # ipset a test 10.0.0.0/24 nomatch
 # ipset t test 10.0.0.1
 10.0.0.1 is NOT in set test.
 # ipset t test 10.0.0.1 nomatch
 10.0.0.1 is in set test.

 # ipset a test 192.168.0.0/24
 # ipset t test 192.168.0.1
 192.168.0.1 is in set test.
 # ipset t test 192.168.0.1 nomatch
 192.168.0.1 is NOT in set test.

 Before the patch the results were

 ...
 # ipset t test 192.168.0.1
 192.168.0.1 is in set test.
 # ipset t test 192.168.0.1 nomatch
 192.168.0.1 is in set test.

netfilter: ipset: Fix serious failure in CIDR tracking

This fixes a serious bug affecting all hash types with a net element -
specifically, if a CIDR value is deleted such that none of the same size
exist any more, all larger (less-specific) values will then fail to
match. Adding back any prefix with a CIDR equal to or more specific than
the one deleted will fix it.

Steps to reproduce:
ipset -N test hash:net
ipset -A test 1.1.0.0/16
ipset -A test 2.2.2.0/24
ipset -T test 1.1.1.1           #1.1.1.1 IS in set
ipset -D test 2.2.2.0/24
ipset -T test 1.1.1.1           #1.1.1.1 IS NOT in set

This is due to the fact that the nets counter was unconditionally
decremented prior to the iteration that shifts up the entries. Now, we
first check if there is a proceeding entry and if not, decrement it and
return. Otherwise, we proceed to iterate and then zero the last element,
which, in most cases, will already be zero.
