fit: check return value of fit_image_get_data_size() 

GCC-10 reports:

In file included from tools/common/image-fit.c:1:
include/image.h: In function ‘fit_image_get_data_and_size’:
./tools/../common/image-fit.c:1015:9: warning: ‘len’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
 1015 |   *size = len;
      |   ~~~~~~^~~~~
./tools/../common/image-fit.c:996:6: note: ‘len’ was declared here
  996 |  int len;
      |      ^~~

Add the missing check of the return value of fit_image_get_data_size().
