net: usb: pegasus: replace simple_strtoul with kstrtouint

simple_strtoul() is deprecated as it has no error checking. Replace it
with kstrtouint() which returns an error code on invalid input, and add
appropriate error handling.

Also add a NULL check before parsing flags, since strsep() can set id
to NULL if the input has fewer tokens than expected.

Preserve the original behavior for a trailing colon by checking *id
before parsing flags, so an empty string results in flags = 0 rather
than an error.
