net: hns3: fix the number of queues actually used by ARQ 



[ Upstream commit 65e61e3c2a619c4d4b873885b2d5394025ed117b ]

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: 07a0556a ("net: hns3: Changes to support ARQ(Asynchronous Receive Queue)")
