commit 834a34edde08ee0748c2d7c35351f879356f4981
Author: Tim Newsome <ti...@si...>

gdb_server,rtos: Differentiate rtos_get_gdb_reg failing and not implemented
If it fails, then pass that failure on. If it's simply not implemented,
then we can fall through and try target_get_gdb_reg_list_noread().
This difference matters when the target representing the current
hwthread is unavailable, but the target that is linked to the gdb
connection is available. In that case we want the operation to return an
error to gdb, instead of reading the register from the target that is
available.
