Philippe Mathieu-Daudé 5e29521a82 hw/avr/boot: Fix memory leak in avr_load_firmware()
The value returned by qemu_find_file() must be freed.

This fixes Coverity issue CID 1430449, which points out
that the memory returned by qemu_find_file() is leaked.

Fixes: Coverity CID 1430449 (RESOURCE_LEAK)
Fixes: 7dd8f6fde4 ('hw/avr: Add support for loading ELF/raw binaries')
