include/linux/log2.h: add missing () around n in roundup_pow_of_two()
[ Upstream commit 428fc0aff4e59399ec719ffcc1f7a5d29a4ee476 ]
Otherwise gcc generates warnings if the expression is complicated.
Fixes: 312a0c170945 ("[PATCH] LOG2: Alter roundup_pow_of_two() so that it can use a ilog2() on a constant")
