nvme: move SPDK_NVME_DEFAULT_RETRY_COUNT out from nvme.h

Browse Source 
SPDK_NVME_DEFAULT_RETRY_COUNT is the default value for each controller, so
we can move it out from public header file, and change the value if users
provide a new one.

"NvmeRetryCount" was deprecated for a long time, so we removed the support
for this configuration option as well.
