libkmod: clear file->memory if map fails
On mmap failure file->memory is set to -1, which we'll happily pass down
to munmap later on.
More importantly, since we do a NULL check in kmod_file_load_contents()
we will exit the function without (re)attempting the load again.
Since we ignore the return code for the load function(s), one can end up
calling kmod_elf_get_memory() and feed that -1 into init_module.
