cnic: Fix L2CTX_STATUSB_NUM offset in context memory.
The BNX2_L2CTX_STATUSB_NUM definition needs to be changed to match
the recent firmware update:
commit 078b0735881c7969aaf21469f3577831cddd9f8c
bnx2: Update firmware to 5.0.0.j3.
Without the fix, bnx2 can crash intermittently in bnx2_rx_int() when
iSCSI is enabled.
