hla_interface: init trst, srst variables.

  There is an remark in jtag_srst and jtag_trst variables declaration:
  /*
   * JTAG adapters must initialize with TRST and SRST de-asserted
   * (they're negative logic, so that means *high*).  But some
   * hardware doesn't necessarily work that way ... so set things
   * up so that jtag_init() always forces that state.
   */

  but in hla_target such forsing is missed and both variables remains
  uninitialized until "reset" command issued, It prevents target polling
  when connecting to running target.
