wifi: ath9k: add range check for conn_rsp_epid in htc_connect_service()

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath9k: add range check for conn_rsp_epid in htc_connect_service()

I found the following bug in my fuzzer:

  UBSAN: array-index-out-of-bounds in drivers/net/wireless/ath/ath9k/htc_hst.c:26:51
  index 255 is out of range for type 'htc_endpoint [22]'
  CPU: 0 UID: 0 PID: 8 Comm: kworker/0:0 Not tainted 6.11.0-rc6-dirty #14
  Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014
  Workqueue: events request_firmware_work_func
  Call Trace:
   <TASK>
   dump_stack_lvl+0x180/0x1b0
   __ubsan_handle_out_of_bounds+0xd4/0x130
   htc_issue_send.constprop.0+0x20c/0x230

   ath9k_wmi_cmd+0x41d/0x610
   ? mark_held_locks+0x9f/0xe0
   ...

Since this bug has been confirmed to be caused by insufficient verification
of conn_rsp_epid, I think it would be appropriate to add a range check for
conn_rsp_epid to htc_connect_service() to prevent the bug from occurring.
