scsi: fusion: fix if-statement empty body warning
When driver debugging is not enabled, change the debug print macros
to use the no_printk() macro.
This fixes a gcc warning when -Wextra is set:
../drivers/message/fusion/mptlan.c:266:39: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
I have verified that there is very little object code change (with
gcc 7.5.0). There are a few changes like:
cmp %a,%b
jl $1
to
cmp %b,%a
jg $1
