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().
Fixes: c3c863880479 ("add FIT data-position & data-offset property support")
