loop: fix printing of the reserved field array items

They are of char type, so "hh" length modifier should be used (otherwise
they are printed incorrectly as they are sign extended implicitly when
passed as printf arguments in case char is a signed type which is true
for most compilers).

* loop.c (decode_loop_info): Change "%#x" printf qualifier to "%#hhx"
in printing routine for array elements of the "reserved" field of
loop_info structure.
