jtag: parse command options in 'swd newdap'
The same code is currently used for commands 'jtag newtap' and
'swd newdap' (plus dapdirect versions), but for SWD case the code
skips the parsing of the command line as not every flag is used.
This has the drawback that syntax errors get unchecked.
Move the check about the transport so the command line get always
parsed even when the corresponding flags are not useful.
