x86/entry: Correct reference to intended CONFIG_64_BIT

Commit in Fixes adds a condition with IS_ENABLED(CONFIG_64_BIT),
but the intended config item is called CONFIG_64BIT, as defined in
arch/x86/Kconfig.

Fortunately, scripts/checkkconfigsymbols.py warns:

64_BIT
Referencing files: arch/x86/include/asm/entry-common.h

Correct the reference to the intended config symbol.
