RDMA/bnxt_re: Fix incorrect errno used in function comments

The function comments in qplib_rcfw.c mention -ETIMEOUT as a
possible return value. However, the correct errno is -ETIMEDOUT.

Update the comments to reflect the proper return value to avoid
confusion for developers and users referring to the code.
