jtag: drivers: stlink: ignore write verify error 

This looks like some inappropriate stlink (mis-)feature and it messes
operations for writing to certain memory-mapped registers.

Discussed at https://forum.sparkfun.com/viewtopic.php?f=18&t=44949 .
Also known to be problematic for working with Kinetis parts.

Reported by robertfoss_ on IRC.
