ima: Introduce ima_dump_measurement()

Browse Source 
Introduce ima_dump_measurement() to simplify the code of
ima_dump_measurement_list() and to avoid repeating the
ima_dump_measurement() code block if iteration occurs on multiple lists.

No functional change: only code moved to a separate function.
