jtag/adi_v5_jtag: fix infinite recursion in jtagdp_transaction_endcheck()

Calling ahbap_debugport_init() is wrong here because the actions
performed by it might lead to jtagdp_transaction_endcheck errors thus
leading to infinite recursion.

The removed code is not needed now because target polling should lead
to reexamination automatically, and both cortex_a and cortex_m call
ahbap_debugport_init() as part of their target examine handler.

This was reported as a real life issue on IRC by Weaselweb with
Cortex-A target. Quitte reports similar results in some circumstances
(adapter_khz too high) with LPC17xx.
