xfs: don't perform discard if the given range length is less than block size
For discard operation, we should return EINVAL if the given range length
is less than a block size, otherwise it will go through the file system
to discard data blocks as the end range might be evaluated to -1, e.g,
# fstrim -v -o 0 -l 100 /xfs7
/xfs7: 9811378176 bytes were trimmed
This issue can be triggered via xfstests/generic/288.
Also, it seems to get the request queue pointer via bdev_get_queue()
instead of the hard code pointer dereference is not a bad thing.

xfs: underflow bug in xfs_attrlist_by_handle()
If we allocate less than sizeof(struct attrlist) then we end up
corrupting memory or doing a ZERO_PTR_SIZE dereference.
This can only be triggered with CAP_SYS_ADMIN.

xfs: simplify xfs_setsize_buftarg callchain; remove unused arg
The "verbose" argument to xfs_setsize_buftarg_flags() has been
unused since:
ffe37436 xfs: stop using the page cache to back the buffer cache
Remove it, and fold the function into xfs_setsize_buftarg()
now that there's no need for different types of callers.
Fix inconsistent comment spacing while we're at it.
