This test fails when xfs is formatted with 64k filesystem block size*.
It fails because the soft quota is not exceeded with the hardcoded 64k
pwrite, thereby, the grace time is not set. Even though soft quota is
set to 12k for uid1, it is rounded up to the nearest blocksize.

*** Report for user quotas on device /dev/sdb3
Block grace time: 7days; Inode grace time: 7days

Adapt the pwrite to do twice the FS block size and set the soft limit
to be 1 FS block and hard limit to be 100 FS blocks. This also gets rid
of harcoded quota limit values.

* This happens even on a 64k pagesize system and it is not related to
  LBS effort.
