[PATCH] libnvdimm, btt: use %z format string modifier for size_t

[Arnd Bergmann <arnd@arndb.de>]

We get a warning about an two incorrect format strings:

drivers/nvdimm/btt.c: In function 'btt_map_init':
include/linux/device.h:1472:23: error: format '%lx' expects argument of type 'long unsigned int', but argument 6 has type 'size_t {aka unsigned int}' [-Werror=format=]

This changes the %lx to %zx as it should be.

Fixes: 86652d2eb347 ("libnvdimm, btt: clean up warning and error messages")
