Commit "xfs: only return -errno or success from attr ->put_listent" changes the
returnvalue of __xfs_xattr_put_listen to 0 in case when there is insufficient
space in the buffer assuming that setting context->count to -1 would be enough,
but all of the ->put_listent callers only check seen_enough. This results in
a failed assertion:
XFS: Assertion failed: context->count >= 0, file: fs/xfs/xfs_xattr.c, line: 175
in insufficient buffer size case.
