jtag: core: report TRST and SRST as asserted only when they really are 

When SRST is never enabled, the global jtag_srst variable is left at its
initial state, that is, -1, and it does _not_ mean SRST is currently
asserted. Same about TRST.

Fixes "reset halt" in cases when srst_pulls_trst but srst usage is not
enabled.
