When refilling freelists for the first time and if it fails, the rxq
is freed and returns ENOMEM. There is a check while freeing hardware rxq
to pass freelist context id if the freelist exists or 0xffff otherwise.
The error path is only reached if freelist exists. So, fix is to remove
the useless check for freelist existence.

Coverity issue: 107108
Fixes: 92c8a63223e5 ("cxgbe: add device configuration and Rx support")
