[RFC PATCH 05/18] arm: cppcheck: fix misra rule 20.7 on arm/include/asm/string.h

[Luca Fancellu <luca.fancellu@xxxxxxx>]

Cppcheck has found a violation of rule 20.7 for the macro memset
about missing parenthesis for the "n" argument, while the parenthesis
are not mandatory because the argument is never used in an
expression, adding them will not harm code and readability, so fix
the finding adding parenthesis for the argument.

Eclair and coverity does not report this finding.
