[RFC 10/32] fs/coda: convert to struct inode_time

[Arnd Bergmann <arnd@arndb.de>]

This converts the coda file system to use inode_time, which we will
need to fix the y2038 limit. However, inode time stamps in coda
are communicated to user space through coda_pioctl() as a 'struct
timespec', so this cannot be fixed for coda without changing the
user space interface.
