The AGFL reservation patches increase the amount of reserved space that
this test needs in order to succeed.  Modify the resblks xfs_io call to
account for the increased per-AG reservation.

Without this change, the dd in the test gets an ENOSPC in the path where
a delalloc is converted to a real allocation.  This results in the test
spinning in the dd command and generating endless xfs_discard_folio
warnings.

Since resblks is supposed to prevent the filesystem from getting empty
enough to hit a case like this, increase it slightly to account for the
modified per-ag reservation size.
