Use a/m/c_time accessor functions

In v6.6-rc5-1-g077c212f0344, one can no longer directly access the
inode m_time and a_time etc. We have to go through these static inline
functions to get to them.

Further back, ctime accessors were added in v6.5-rc1-7-g9b6304c1d537,
and need to be applied as well.
