bnxt_re: set errno to 'EINVAL' in cq creation bad flow

Currently when the user creates a CQ with CQEs greater than
the device max_depth bnxt_re lib will catch this error flow
and return immediately without creating a CQ, some test cases
expect to have EINVAL in errno which is not set by bnxt.

This patch updates the bnxt_re lib to set the errno to EINVAL in case of
bad cq creation flow.
