From: "Bernard.Iremonger" <Bernard.iremonger@intel.com>

The dyn_tokens array is initialised at the beginning of
the cmdline_parse function. However when the inst_num
variable is incremented later in the function the
dyn_tokens array is not reinitialised so the tokens
from the previous command are used.

The solution is to initialise the dyn_tokens array in
the while(inst) loop.

Fixes: 4fffc05a2b2c ("cmdline: support dynamic tokens")
