Fix check_ssh_injection in cinder/utils

check_ssh_injection is used to prevent commands being modified using
specially constructed strings containing special characters.

The function includes a loop over the special characters to compare
them against each arg. If the special character is the same as the arg
it gets ignored.

This commit modifies this part of the function so that args that are
exactly equal to one of the special characters will cause an exception
to be raised.
