gdbserver: fix typo that broke read/write watchpoint 

It looks like a bugfix from normal breakpoints was not
copied over.

Do not use clever mathematics and assumptions to convert from
GDB enum for break/watchpoints to OpenOCD enum.

Drop connection upon unknown breakpoint type, this code path
was not really considered by the previous code I think.
