xfs: fix remount rw with unrecognized options
commit 6c5e51dae2c37127e00be392f40842e08077e96a upstream
When we skip unrecognized options in xfs_fs_remount we should just break
out of the switch and not return because otherwise we may skip clearing
the xfs-internal read-only flag. This will only show up on some
operations like touch because most read-only checks are done by the VFS
which thinks this filesystem is r/w. Eventually we should replace the
XFS read-only flag with a helper that always checks the VFS flag to make
sure they can never get out of sync.
Bug reported and fix verified by Marcel Beister on #xfs.
Bug fix verified by updated xfstests/189.
