Subject: [RFC 26/32] reiserfs: convert to struct inode_time

reiserfs uses unsigned 32-bit seconds for inode timestamps, which will work
for the next 92 years, but the VFS uses struct timespec for timestamps,
which is only good until 2038 on 32-bit CPUs.

This gets us one small step closer to lifting the VFS limit by using
struct inode_time in reiserfs.
