ext4: fix fast commit alignment issues
Fast commit recovery data on disk may not be aligned. So, when the recovery code reads it, this patch makes sure that fast commit info found on-disk is first memcpy-ed into an aligned variable before accessing it. As a consequence of it, we also remove some macros that could resulted in unaligned accesses.
