locks: ensure vfs_test_lock() never returns FILE_LOCK_DEFERRED
FILE_LOCK_DEFERRED can be returned when creating or removing a lock, but
not when testing for a lock. This support was explicitly removed in
Commit 09802fd2a8ca ("lockd: rip out deferred lock handling from testlock codepath")
However the test in nlmsvc_testlock() suggests that it *can* be returned,
only nlm cannot handle it.
To aid clarity, remove the test and instead put a similar test and
warning in vfs_test_lock(). If the impossible happens, convert
FILE_LOCK_DEFERRED to -EIO.
