rS302104: [iwm] Use mbuf for large firmware commands, like OpenBSD does.

Summary

We also need to consider the size of large firmware commands in iwm_alloc_tx_ring(), in the dma tag creation, when qid == IWM_MVM_CMD_QUEUE. The old code apparently only allocated a 2KB (MCLBYTES) sized buffer when it actually expected 4KB.

Obtained from: DragonFlyBSD 65b2e1ba01c1ac9098eebea118d71cbc78eac25a

Test Plan

Tested on Intel AC 7260.
