[PULL 13/30] target/ppc: fix exception error code in spr_write_excp_vect

Subject: [PULL 13/30] target/ppc: fix exception error code in spr_write_excp_vector

From: Matheus Ferst <matheus.ferst@eldorado.org.br>

The 'error' argument of gen_inval_exception will be or-ed with
POWERPC_EXCP_INVAL, so it should always be a constant prefixed with
POWERPC_EXCP_INVAL_. No functional change is intended,
spr_write_excp_vector is only used by register_BookE_sprs, and
powerpc_excp_booke ignores the lower 4 bits of the error code on

Also, take the opportunity to replace printf with qemu_log_mask.
