drivers:misc: ti-st: fix skipping of change remote baud

Before the incrementing of ptr in skip_change_remote_baud,
it points to cur_action, but the increment is done by
the size of nxt_action instead. This could cause ptr
to not point to a bts_action structure, which is
harmful for the increment of ptr done in download_firmware.
Therefore, the skipping is first done for cur_action.
