[PATCH net 5/6] iavf: fix ASQ command buffer leak on init failure

From: Xuanqiang Luo <redacted>

iavf_alloc_adminq_asq_ring() allocates cmd_buf before the remaining ASQ
resources. If iavf_alloc_asq_bufs() or iavf_config_asq_regs() fails, the
unwind path elides cmd_buf while freeing the other allocations.

The ASQ count is not set until initialization succeeds, so the shutdown
path cannot reclaim the buffer. Free cmd_buf in the common unwind path.
