The local variables 'rotator' and 'rotate' (used for the progress
indicator) aren't used on s390. Building the kernel with W=1 generates
the following warning:
init/do_mounts_rd.c:192:17: warning: variable 'rotate' set but not used [-Wunused-but-set-variable]
192 | unsigned short rotate = 0;
| ^
1 warning generated.
Remove the preprocessor directives and use the IS_ENABLED(CONFIG_S390)
macro instead, allowing the compiler to optimize away unused variables
and avoid the warning on s390.
