am7xxx-play: fix a possible case of use before initialization

The got_packet variable is assigned inside an internal "if" of the while
loop, but it is also used in the checks at the end of the while loop,
and it is possible to get to this part before having ever assigned the
variable, so in order to behave correctly initialize the variable before
the loop starts.
