mana_create_rxq() returns a struct mana_rxq pointer and returns NULL on
any failure. The caller, mana_add_rx_queues(), cannot tell what went
wrong and hardcodes the error as -ENOMEM. As a result the actual failure
reported by the lower layers (for example -EPROTO from a failed HW
request) is masked and every RX queue creation failure looks like an
out-of-memory error.
Return an ERR_PTR() encoded error code from mana_create_rxq() on failure
instead of NULL. The caller now propagates the returned error code
directly instead of substituting -ENOMEM.
Fixes: ca9c54d2d6 ("net: mana: Add a driver for Microsoft Azure Network Adapter (MANA)")
