wifi: brcmfmac: fix regression for Broadcom PCIe wifi devices

Browse Source 
commit ed05cb177a upstream.

A sanity check was introduced considering maximum flowrings above
256 as insane and effectively aborting the device probe. This
resulted in regression for number of users as the value turns out
to be sane after all.

Fixes: 2aca4f3734 ("brcmfmac: return error when getting invalid max_flowrings from dongle")
