Try fallback drivers if global init for preferred drivers fails
Driver global init was considered a hard failure. Thus if, for example, you used the Broadcom STA driver and didn't have nl80211 or cfg80211 loaded into the kernel, and specified a driver value of "nl80211,wext", the nl80211 driver's global init would fail with the following message: nl80211: 'nl80211' generic netlink not found Failed to initialize driver 'nl80211' but since global init was a hard failure, creating the supplicant interface would fail and the WEXT driver would not be tried. Give other drivers a chance instead. Signed-hostap: Dan Williams <dcbw@redhat.com> intended-for: hostap-1
