e2fsck: fix unaligned accesses to ext4_fc_add_range and fc_raw_inode

These fast commit related structures can be unaligned on disk.  So we
need to avoid accessing these structures directly, and first copy
them to memory which we know is appropriately aligned.

This fixes an e2fsck crash while running the j_recovery_fast_commit
regression test on a sparc64 system.
