staging/lustre: use 64-bit timestamps for mdc

Browse Source 
These three are timestamps that are sent over the wire in mdc_lib
and the obd logging 64-bit values, but are generated using the 32-bit
get_seconds() function, which will eventually overflow.

Changing them to use 64-bit ktime_get_real_seconds() solves the problem.
