Subject: [PATCH] x86/KASLR: always return a value from process_mem_region

When compiling with -Wreturn-type, clang warns:

arch/x86/boot/compressed/kaslr.c:704:1: warning: control may reach end of
      non-void function [-Wreturn-type]

This function's return statement should probably have been placed
outside the #endif, so move it there
