[PATCH] orinoco: fix BAP0 offset error after several days of operation

After several days of operation of Netgear MA311 card, the card becomes
to seek improperly and needs reset. This patch tries to reset the card
when this situation occurs.

Mar  9 06:45:16 berkeley kernel: hermes @ f992a000: BAP0 offset error: reg=0x4044 id=0x128 offset=0x44
