ext4: optimize ext4_should_retry_alloc() to improve ENOSPC performance
If there are no pending blocks to be released after a commit, forcing
a journal commit has no hope of helping. It's possible that a commit
had just completed, so if there are now free blocks available for
allocation, it's worth retrying the commit.
