This commit fixes a small issue which causes both zfs receive and rollback operations to incorrectly increase the "filesystem_count" property value. This change also adds a new test group "limits" to the ZFS Test Suite to exercise both filesystem_count/limit and snapshot_count/limit functionality.

# DESCRIPTION:
|
|
# ZFS 'filesystem_limit' is enforced when executing various actions
|
|
#
|
|
# STRATEGY:
|
|
# 1. Verify 'zfs create' and 'zfs clone' cannot exceed the filesystem_limit
|
|
# 2. Verify 'zfs rename' cannot move filesystems exceeding the limit
|
|
# 3. Verify 'zfs receive' cannot exceed the limit
|
