5b1e985f76 RDMA/irdma: Skip CQP ring during a reset 
Due to duplicate reset flags, CQP commands are processed during reset.

This leads CQP failures such as below:

 irdma0: [Delete Local MAC Entry Cmd Error][op_code=49] status=-27 waiting=1 completion_err=0 maj=0x0 min=0x0

Remove the redundant flag and set the correct reset flag so CPQ is paused
during reset

7364e74d48 RDMA/irdma: Remove use of kmap() 
kmap() is being deprecated and will break uses of device dax after PKS
protection is introduced.[1]

The kmap() used in the irdma CM driver is thread local.  Therefore
kmap_local_page() is sufficient to use and may provide performance
benefits as well.  kmap_local_page() will work with device dax and pgmap
protected pages.

Use kmap_local_page() instead of kmap().
