LU-3852 tests: skip tests with large file when no room

Strengthen sanity-hsm sub-tests using large files by skipping
then if not enough space instead to fail.

Also re-enable test_251, and test_[200,221,223b] (for LU-4178),
who have all been wrongly disabled because of their multiple
failures on an auto-test node with very low disk space for the
Servers VMs!!

Also fix a bug in sanity/test_56w that should not be run if
$OSTCOUNT < 2, that was triggered due to my very restictive
test environment osscount/ostcount=1 to limit the Lustre FS size
as much as possible.

Test-Parameters: ostcount=1 ostsizegb=1 envdefinitions=SLOW=yes
Test-Parameters: osscount=1 mdscount=1 testlist=sanity-hsm

LU-5771 ldiskfs: cleanup orphan inode in error path

Commit from upstream: 4538821993f4486c76090dfb377c60c0a0e71ba3

There were some error paths in ext4_delete_inode() which was not
dropping the inode from the orphan list.  This could lead to a BUG_ON
on umount when the orphan list is discovered to be non-empty.

LU-5461 mdc: don't add to page cache upon failure

Reading directory pages may fail on MDS, in this case client should
not cache a non-up-to-date directory page, because it will cause
a later read on the same page fail.

Add sanity 242 for this.
