edid: silence a stringop-overflow warning
Simplify the code that doesn't need strncpy() since length of string
is already computed.
/home/elmarco/src/qemu/hw/display/edid-generate.c: In function 'edid_desc_text':
/home/elmarco/src/qemu/hw/display/edid-generate.c:168:5: error: 'strncpy' specified bound depends on the length of the source argument [-Werror=stringop-overflow=]
strncpy((char *)(desc + 5), text, len);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/home/elmarco/src/qemu/hw/display/edid-generate.c:164:11: note: length computed here
len = strlen(text);
^~~~~~~~~~~~
cc1: all warnings being treated as errors
