arm64/sve: Move sve_free() into SVE code section
If CONFIG_ARM64_SVE is not set:
arch/arm64/kernel/fpsimd.c:294:13: warning: ‘sve_free’ defined but not used [-Wunused-function]
Fix this by moving sve_free() and __sve_free() into the existing section
protected by "#ifdef CONFIG_ARM64_SVE", now the last user outside that
section has been removed.
Fixes: a1259dd80719 ("arm64/sve: Delay freeing memory in fpsimd_flush_thread()")
