scsi: ibmvfc: extend ibmvfc_debug visibility to ibmvfc-nvme.h

Browse Source 
Export ibmvfc_debug so the NVMe support code can use the
existing ibmvfc_dbg logging macro.

The debug control variable is currently file-local to the core driver,
which prevents protocol-specific code in ibmvfc-nvme.c from using the
shared debug infrastructure. Make the variable global within the module
and declare it in ibmvfc-nvme.h.
