Remove failsafe reset code from HandleResetConfig
Remove failsafe reset code from HandleResetConfig

If any failsafe is active when reset-config is called, it should not be
reset or cancelled. The same applies for HandleResetConfigConnectionClose.

This change also removes error handling that was checking for
WEAVE_ERROR_NOT_IMPLEMENTED, which was not quite correct.
