lib: at_host: fix unresponsiveness after memory error

evenl · rlubos · commit f40a6a81cb33 · 2019-06-28T18:40:00.000+02:00
The AT host library driver did not enable the
uart reception interrupt when the at_write_cmd
function failed because of a non-AT related issue.
It will now treat such errors as the generic
AT error.
