[SCSI] lpfc driver 8.0.30 : convert to use of int_to_scsilun()

Replace use of lpfc_put_lun with midlayer's int_to_scsilun

Remove driver's local definition of lpfc_put_lun (which converts an
int back to a 64-bit LUN) and replace it's use with the recently added
int_to_scsilun function provided by the midlayer.

Note: Embedding midlayer structure in our structure caused
need for more files to include midlayer headers.
