ext4: fix the number of credits needed for ext4_unlink() and ext4_rmdir()
The ext4_unlink() and ext4_rmdir() don't actually release the blocks associated with the file/directory. This gets done in a separate jbd2 handle called via ext4_evict_inode(). Thus, we don't need to reserve lots of journal credits for the truncate. Note that using too many journal credits is non-optimal because it can leading to the journal transmit getting closed too early, before it is strictly necessary.
