xfs: free the xfs_mount in ->kill_sb
As a rule of thumb everything allocated to the fs_context and moved into
the super_block should be freed by ->kill_sb so that the teardown
handling doesn't need to be duplicated between the fill_super error
path and put_super. Implement a XFS-specific kill_sb method to do that.
