[PATCH] staging: octeon: remove unnecessary parentheses

[Tianbo Fu <3064575448@qq.com>]

checkpatch.pl reports multiple CHECKs for unnecessary parentheses
around single conditions. Remove them to improve readability.

No functional change.

Hi Greg,

I removed some unnecessary parentheses and compiled this on my
x86_64 computer successfully. Please let me know if anything
needs fixing.

Thanks,
Tianbo Fu
