When cleaning up a test case standardize on using the convention:
datasetexists $ds && destroy_dataset $ds <flags>
By using 'destroy_dataset' instead of 'log_must zfs destroy' we ensure
that the destroy is retried in the event that a ZFS volume is busy.
This helps ensures ensure tests are fully cleaned up and prevents false
positive test failures on Linux.
Note that all of the tests which used 'zfs destroy' in cleanup have
been updated even if they don't use volumes. This was done to
clearly establish the expected convention.

# Description:
|
|
# Verify that nopwrite works for sync writes
|
|
#
|
|
# Strategy:
|
|
# 1. Create an origin fs with compression and sha256.
|
|
# 2. Clone origin such that it inherits the properties.
|
|
# 3. Use dd with the sync flag to test the sync write path.
