[PATCH v2 07/17] md/raid5-ppl: Drop unused argument from ppl_handle_flush_request()

ppl_handle_flush_request() takes an struct r5log argument but doesn't
use it. It has no buisiness taking this argument as it is only used
by raid5-cache and has no way to derference it anyway. Remove
the argument.

No functional changes intended.
