[PATCH 1/8] lpfc: Revert LOG_TRACE_EVENT back to LOG_INIT prior to driver_resource_setup

In cases when lpfc_enable_pci_dev fails, lpfc_printf_log with
LOG_TRACE_EVENT set will call lpfc_dmp_dbg which uses the
phba->port_list_lock.

However, phba->port_list_lock does not get initialized until
lpfc_setup_driver_resource_phase1. Thus, any initialization routine with
LOG_TRACE_EVENT log message prior to lpfc_setup_driver_resource_phase1
will crash.

Revert LOG_TRACE_EVENT back to LOG_INIT for all log messages in routines
prior to lpfc_setup_driver_resource_phase1.
