tools: mkimage: Print human readable error when -d is not specified
When asking mkimage to create a new image file and option -d is not
specified then mkimage show human unfriendly error message:
mkimage: Can't open (null): Bad address
Without debugger it is hard to debug what is the issue. Function open() is
being called with file name set to NULL. So add a check for this and if it
happens then show human readable message that option -d was not specified.
