x86, dax, pmem: remove indirection around memcpy_from_pmem()
memcpy_from_pmem() maps directly to memcpy_mcsafe(). The wrapper serves no real benefit aside from affording a more generic function name than the x86-specific 'mcsafe'. However this would not be the first time that x86 terminology leaked into the global namespace. For lack of better name, just use memcpy_mcsafe() directly. This conversion also catches a place where we should have been using plain memcpy, acpi_nfit_blk_single_io().
