scsi: sym53c416: avoid section mismatch with LTO

Building with link time optimizations produces a false-positive section
mismatch warning:

WARNING: vmlinux.o(.data+0xf8c8): Section mismatch in reference from the variable driver_template.lto_priv.6915 to the function .init.text:sym53c416_detect()
The variable driver_template.lto_priv.6915 references
the function __init sym53c416_detect()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

The ->detect callback is always entered from the init_this_scsi_driver()
init function, but apparently LTO turns the optimized direct function
call into an indirect call through a non-__initdata pointer.

All drivers using init_this_scsi_driver() are for ancient hardware,
and most don't mark the detect() callback as __init(), so I'm
just removing the annotation here to kill off the warning instead
of doing a larger rework.
