scsi: mpt3sas: Fix event callback log_code value handling

Browse Source 
In mpt3sas_scsih_event_callback(), fix a sparse warning when testing the
event log code value by replacing the use of a pointer to the address
storing the event log code with a log code local variable. Doing so,
le32_to_cpu() is used when the log code value is assigned, avoiding a
sparse warning.
