[PATCH] x86-64: Simplify minimum ISA check ifdef conditional with if

[Sunil K Pandey <skpgkp2@gmail.com>]

Replace minimum ISA check ifdef conditional with if.  Since
MINIMUM_X86_ISA_LEVEL and AVX_X86_ISA_LEVEL are compile time constants,
compiler will perform constant folding optimization getting same result.
