xfs: don't perform discard if the given range length is less than block size
commit f9fd0135610084abef6867d984e9951c3099950d upstream.
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,
/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.
