[PATCH]: Remove redundant #ifdef CONFIG_SPARC64 check

[PATCH]: Remove redundant #ifdef CONFIG_SPARC64 check

[Sarah Nadi]

From: Sarah Nadi<snadi@uwaterloo.ca>

Summary: Unnecessary #ifdef check in arch/sparc/kernel/jump_label.c

Problem description: The #ifdef CONFIG_SPARC64 is unnecessary since the file is only compiled when CONFIG_SPARC64 is selected. Leaving it in makes the
#ifdef block always selected while the #else block is never selected. Suggested patch to remove unneccesary check below.

This is there so that sparc 32-bit support is easy to add for someone
so inclined, do not remove this.
