x86/hyperv: Add missing 'inline' to hv_snp_boot_ap() stub

Browse Source 
When building without CONFIG_AMD_MEM_ENCRYPT, there are several
repeated instances of -Wunused-function due to missing 'inline' on
the stub of hy_snp_boot_ap():

  In file included from drivers/hv/hv_common.c:29:
  ./arch/x86/include/asm/mshyperv.h:272:12: error: 'hv_snp_boot_ap' defined but not used [-Werror=unused-function]
    272 | static int hv_snp_boot_ap(int cpu, unsigned long start_ip) { return 0; }
        |            ^~~~~~~~~~~~~~
  cc1: all warnings being treated as errors

Add 'inline' to fix the warnings.
