target/xtensa: drop gen_io_end call
Since commit
ba3e7926691e ("icount: clean up cpu_can_io at the entry to the block")
it has been unnecessary for target code to call gen_io_end() after an IO
instruction in icount mode; it is sufficient to call gen_io_start()
before it and to force the end of the TB.
Remaining call in xtensa target translator is for the opcodes that may
change IRQ state. All of them end current TB, so gen_io_end is not
needed. Drop gen_io_end call from the xtensa target translator.
