nvme_spec: Add two macros to check status of command completion

Browse Source 
This patch adds two macros, spdk_nvme_cpl_is_success and
spdk_nvme_cpl_is_pi_error. The former will be used to check if
checked read completes normally, and the latter will be used to
know if PI verification should be done.
