platform/x86: intel_pmc_core: Fix "unsigned 'ret' is never less than zero" smatch warning
Change the type of ret form a size_t to a ssize_t, matching the prototype
of simple_write_to_buffer(), fixing this warning reported by smatch:
drivers/platform/x86/intel_pmc_core.c:1369 pmc_core_lpm_latch_mode_write() warn: unsigned 'ret' is never less than zero.
