Dipayaan Roy 3985c9a56d net: mana: remove double CQ cleanup in mana_create_rxq error path 
In mana_create_rxq(), the error cleanup path calls mana_destroy_rxq()
followed by mana_deinit_cq(). This is incorrect for two reasons:

1. mana_destroy_rxq() already calls mana_deinit_cq() internally,
   so the CQ's GDMA queue is destroyed twice.

2. mana_destroy_rxq() frees the rxq via kfree(rxq) before returning.
   The subsequent mana_deinit_cq(apc, cq) then operates on freed memory
   since cq points to &rxq->rx_cq, which is embedded in the
   already-freed rxq structure — a use-after-free.

Remove the redundant mana_deinit_cq() call from the error path since
mana_destroy_rxq() already handles CQ cleanup. mana_deinit_cq() is
itself safe for an uninitialized CQ as it checks for a NULL gdma_cq
before proceeding.

Fixes: ca9c54d2d6 ("net: mana: Add a driver for Microsoft Azure Network Adapter (MANA)")
