clang is not happy about set but unused variable:

kernel/kexec_core.c:745:16: error: variable 'maddr' set but not used [-Werror,-Wunused-but-set-variable]
  745 |         unsigned long maddr;
      |                       ^
1 error generated.

Fix the compilation breakage (`make W=1` build) by removing unused variable.

As Nathan noted, GCC 16 produces the similar warning;

Fixes: f4fecb50d6e1 ("kexec_core: remove superfluous page offset handling in segment loading")

v2: fixed Fixes (Nathan), added a note about GCC (Nathan), added tag (Nathan)
