cpumf/pai: Omit file write progress information

Browse Source 
During recording, progress information is displayed on the screen
on how many event have been processed and at which offset these
events have been extracted from the ring buffer.

This information is usually of no interest to the user. Omit this
data and only print them when requested via verbose flag.
