Subject: net: hns3: fix the number of queues actually used by ARQ
Patch-mainline: v5.11-rc3
Git-commit: 65e61e3c2a619c4d4b873885b2d5394025ed117b
References: bsc#1104353 FATE#326415

HCLGE_MBX_MAX_ARQ_MSG_NUM is used to apply memory for the number
of queues used by ARQ(Asynchronous Receive Queue), so the head
and tail pointers should also use this macro.

Fixes: 07a0556a3a73 ("net: hns3: Changes to support ARQ(Asynchronous Receive Queue)")
