Quota: fix testcases not to send parallel writes for accurate
quota enforcement
Currently quota enforcer doesn't consider parallel writes
and allows quota to exceed limit where there are high rate
of parallel writes. Bug# 1223658 tracks the issue.
This patch fixes the spurious failures by not sending
parallel writes.
Using O_SYNC and O_APPEND flags and block size
not more that 256k (For higher block size NFS client
splits the block into 256k chinks and does parallel writes)
