Christoph Hellwig 76ca4c238c xfs: always take the iolock around xfs_setattr_size
There is no reason to conditionally take the iolock inside xfs_setattr_size
when we can let the caller handle it unconditionally, which just incrases
the lock hold time for the case where it was previously taken internally
by a few instructions.
