scsi: bfa: improve bfa_ioc_send_enable/disable data
In bfa_ioc_send_enable, we use the deprecated do_gettimeofday() function to read the current time. This is not a problem, since the firmware interface is already limited to 32-bit timestamps, but it's better to use ktime_get_seconds() and document what the limitation is. I noticed that I did the same change in commit a5af83925363 ("bna: avoid writing uninitialized data into hw registers") for the ethernet driver. That commit also changed the "disable" funtion to initialize the data we pass to the firmware properly, so I'm doing the same thing here.
