coding style: remove useless break after a goto or return 

In a switch/case statement, a break placed after a goto or return
is never executed.
The script checkpatch available in Linux kernel v5.1 issues a
warning for such unused break statements.
In the process of reviewing the new checkpatch for its inclusion
in OpenOCD, let's get rid of these warnings.

The script checkpatch is unable to fixup automatically this case.
Thanks to having "break" command using a single code line, this
patch has been generated using the script below:

	find src/ -type f -exec ./tools/scripts/checkpatch.pl -q \
	 --types UNNECESSARY_BREAK -f {} \; \
	| sed -n '/^#/{s/^.*FILE: //;s/:$//;s/:/ /;p}' \
	| awk 'function P() {print "sed -i '\''"b"'\'' "a};
	       {
	         if ($1!=a) {
	           if (a) {P()};
	           a=$1;
	           b=$2"{d}";
	         } else {
	           b=b";"$2"{d}"
	         }
	       };
	       END {P()}'
