powerpc/xmon: Fix disassembly since printf changes
The recent change to add printf annotations to xmon inadvertently made
the disassembly output ugly, eg:
c00000002001e058 7ee00026 mfcr r23
c00000002001e05c fffffffffae101a0 std r23,416(r1)
c00000002001e060 fffffffff8230000 std r1,0(r3)
The problem being that negative 32-bit values are being displayed in
full 64-bits.
The printf conversion was actually correct, we are passing unsigned
long so it should use "lx". But powerpc instructions are only 4 bytes
and the code only reads 4 bytes, so inst should really just be
unsigned int, and that also fixes the printing to look the way we
want:
c00000002001e058 7ee00026 mfcr r23
c00000002001e05c fae101a0 std r23,416(r1)
c00000002001e060 f8230000 std r1,0(r3)
Fixes: e70d8f55268b ("powerpc/xmon: Add __printf annotation to xmon_printf()")
