scsi: scsi_lib: Add kernel-doc for exported functions 

JIRA: https://issues.redhat.com/browse/RHEL-86156
Upstream Status: From upstream linux mainline

Add kernel-doc for scsi_failures_reset_retries() and scsi_alloc_request()
since these are exported.  This allows them to be part of the SCSI
driver-api docbook.

Fix kernel-doc comments for scsi_vpd_tpg_id() [add kernel-doc for one
parameter and fix a typo].
