qapi: Fix QemuOpts visitor regression on unvisited input 

An off-by-one in commit 15c2f669e meant that we were failing to
check for unparsed input in all QemuOpts visitors.  Recent testsuite
additions show that fixing the obvious bug with bogus fields will
also fix the case of an incomplete list visit; update the tests to
match the new behavior.

Simple testcase:

./x86_64-softmmu/qemu-system-x86_64 -nodefaults -nographic -qmp stdio -numa node,size=1g

failed to diagnose that 'size' is not a valid argument to -numa, and
now once again reports:

qemu-system-x86_64: -numa node,size=1g: Invalid parameter 'size'
