libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk for Seagate Momentus SpinPoint M8 (2BA30001)

commit b28a613e9138e4b3a64649bd60b13436f4b4b49b upstream.

Via commit 87809942d3fa "libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk
for Seagate Momentus SpinPoint M8" we added a quirk for disks named
"ST1000LM024 HN-M101MBB" with firmware revision "2AR10001".

As reported on https://bugzilla.redhat.com/show_bug.cgi?id=1073901,
we need to also add firmware revision 2BA30001 as it is broken as well.

NFS: Fix a delegation callback race

commit 755a48a7a4eb05b9c8424e3017d947b2961a60e0 upstream.

The clean-up in commit 36281caa839f ended up removing a NULL pointer check
that is needed in order to prevent an Oops in
nfs_async_inode_return_delegation().
