[PATCH] ubiformat.c: fix printf(%d, size_t) warning

[Mike Frysinger]

A size_t should be printed using %zu (unsigned size_t) rather than %d.  This
fixes the following warning on my system:
gcc -O2 -Werror -Wall -Iinclude -Isrc -I../../include src/ubiformat.c -c -o ubiformat.o
cc1: warnings being treated as errors
src/ubiformat.c: In function ‘read_all’:
src/ubiformat.c:345: error: format ‘%d’ expects type ‘int’, but argument 3 has type ‘size_t’
src/ubiformat.c:352: error: format ‘%d’ expects type ‘int’, but argument 3 has type ‘size_t’
make: *** [ubiformat.o] Error 1
