[PATCH 4.12] brcmfmac: get rid of brcmf_txflowblock helper function

["Rafał Miłecki" <zajec5@gmail.com>]

From: Rafał Miłecki <rafal@milecki.pl>

This helper function is pretty trivial and we can easily do without it.
What's important though it's one of FWS (Firmware Signalling)
dependencies in core.c. The plan is to make FWS required by BCDC only so
we don't have to use/compile it when using msgbuf.
