block: remove superfluous param in blk_fill_rwbs()

Browse Source 
The last parameter for the function blk_fill_rwbs() was added in
5782138e47 ("tracing/events: convert block trace points to
TRACE_EVENT()") in order to signal read request and use of that parameter
was replaced with using switch case REQ_OP_READ with
1b9a9ab78b ("blktrace: use op accessors"), but the parameter was never
removed.

Remove the unused parameter and adjust the respective call sites.

Fixes: 1b9a9ab78b ("blktrace: use op accessors")
