Subject: [RFC v2a 09/12] fs: ceph: Change encode and decode functions to use vfs_time

Encode is used for iattr times, inode times and current
filesystem times.
Decode is mostly used for inode times.
Hence, these need to use vfs_time to switch to 64 bit times
along with vfs.

Decode is also used for keepalive times and processing
authentication tickets. Since inode times also use same functions
it is necessary to use vfs_time here as well.
