firmware: make sure the fw file size is not 0
If the requested firmware file size is 0 bytes in the filesytem, we
will try to vmalloc(0), which causes a warning:
vmalloc: allocation failure: 0 bytes
kworker/1:1: page allocation failure: order:0, mode:0xd2
__vmalloc_node_range+0x164/0x208
__vmalloc_node+0x4c/0x58

process_one_work+0x1d0/0x750

To fix this, check whether the file size is less than or equal to zero
in fw_read_file_contents().
