    We do not need the ilock for most checks done in the beginning of
    xfs_setattr_size.  Replace the long critical section before starting the
    transaction with a smaller one around xfs_zero_eof and an optional one
    inside xfs_qm_dqattach that isn't entered unless using quotas.  While
    this isn't a big optimization for xfs_setattr_size itself it will allow
    pushing the ilock into xfs_zero_eof itself later.
