Removed node reset from doReset and moved it into dedicated function

A "normal" error reset should not trigger a node reset. However, this
option is still available via a dedicated PV xx:NodeReset and a
corresponding function in masterMacsAxis.

 ### How to build it
 
-This driver can be compiled and installed by running `make install` from the same directory where the Makefile is located. However, since it uses the git submodule sinqMotor, make sure that the correct version of the submodule repository is checked out AND the change is commited (`git status` shows no non-committed changes). Please see the section "Usage as static dependency" in https://git.psi.ch/sinq-epics-modules/sinqmotor/-/blob/main/README.md for more details.
