[PATCH 07/11] Input: ims-pcu - fix logic error in packet reset

[Dmitry Torokhov]

ims_pcu_reset_packet() incorrectly sets have_stx to true, which implies
that the start-of-packet delimiter has already been received. This
causes the protocol parser to skip waiting for the next STX byte and
potentially process garbage data.

Correctly set have_stx to false when resetting the packet state.

Fixes: 875115b82c29 ("Input: ims-pcu - fix heap-buffer-overflow in ims_pcu_process_data()")
