Subject: [PATCH] libertas sdio: remove CMD_FUNC_INIT call

It actually times out on a 8688 present in GuruPlug with sd8688.bin
(md5=7233401e9687f8c880da547beed4324e) firmware (that's present in
linux-firmware tree), but the adapter works fine.

For that firmware times out with libertas_uap [1] as well, though it succeeds
with sd8688_ap.bin (md5=52cd8f8296b9a7e1d3835d57416256b2) that was originally
shipped with GuruPlug. That firmware is not in linux-firmware tree and btmrvl
driver might win the race programming the 8688 with sd8688.bin anyway.
