asm-generic: percpu: avoid Wshadow warning
Nesting macros that use the same local variable names causes
warnings when building with "make W=2":
include/asm-generic/percpu.h:117:14: warning: declaration of '__ret' shadows a previous local [-Wshadow]
include/asm-generic/percpu.h:126:14: warning: declaration of '__ret' shadows a previous local [-Wshadow]
These are fairly harmless, but since the warning comes from
a global header, the warning happens every time the headers
are included, which is fairly annoying.
Rename the variables to avoid shadowing and shut up the warning.
