hw/ppc/spapr.c: fail early if no firmware found in machine_init()

Browse source 
The firmware check consists on a file search (qemu_find_file) and load
it via load_imag_targphys(). This validation is not dependent on any
other machine state but it currently being done at the end of
spapr_machine_init(). This means that we can do a lot of stuff and end
up failing at the end for something that we can verify right out of the
gate.

Move this validation to the start of spapr_machine_init() to fail
earlier.  While we're at it, use g_autofree in the 'filename' pointer.
