brcmfmac: Remove firmware-loading code duplication

jwrdegoede · Kalle Valo · commit a1a3b7621638 · 2018-11-06T18:50:14.000+02:00
brcmf_fw_request_next_item and brcmf_fw_request_done both have identical
code to complete the fw-request depending on the item-type.

This commit adds a new brcmf_fw_complete_request helper removing this code
duplication.
