Joakim Bech 72b425b640 ieee1275: fix build regression in of_path_of_nvme
The of_path_of_nvme function (commit 2391d57, ieee1275: add nvme
support within ofpath) introduced a build regression:
    grub-core/osdep/linux/ofpath.c:365:21: error: comparison between pointer
    and zero character constant [-Werror=pointer-compare]
       if ((digit_string != '\0') && (*part_end == 'p'))

Update digit_string to compare against the char instead of the pointer.
