[PATCH] x86/boot/KASLR: Fix unused variable warning

[Zhenzhong Duan]

This patch fixes below warning by moving variable 'i':
arch/x86/boot/compressed/kaslr.c:698:6: warning: unused variable âiâ
[-Wunused-variable]

Also use true/false instead of 1/0 for boolean return.

Fixes: 690eaa532057 ("x86/boot/KASLR: Limit KASLR to extract the
kernel in immovable memory only")
