ptp: Fix resource leak in case of error

A call to 'ida_simple_remove()' is missing in the error handling path.

This as been spotted with the following coccinelle script which tries to
detect missing 'ida_simple_remove()' call in error handling paths.

expression x;

*   x = ida_simple_get(...);

    ...
    if (...) {
       ...
       goto l;
    }
    ...
*   l: ... when != ida_simple_remove(...);
