pmem: remove layer when calling arch_has_wmb_pmem()
Prior to this change arch_has_wmb_pmem() was only called by arch_has_pmem_api(). Both arch_has_wmb_pmem() and arch_has_pmem_api() checked to make sure that CONFIG_ARCH_HAS_PMEM_API was enabled. Instead, remove the old arch_has_wmb_pmem() wrapper to be rid of one extra layer of indirection and the redundant CONFIG_ARCH_HAS_PMEM_API check. Rename __arch_has_wmb_pmem() to arch_has_wmb_pmem() since we no longer have a wrapper, and just have arch_has_pmem_api() call the architecture specific arch_has_wmb_pmem() directly.
