Staging: bcm: remove unneeded NULL check

The error handling here is wrong.  If psIntfAdapter were NULL then we
would have a NULL dereference in the debug output on the error path.
But this function is only called from usbbcm_device_probe() when
psIntfAdapter is non-NULL.

Since the check isn't needed and I removed it instead of fixing it.
