Fix zfs-dkms .deb package warning in prerm script

Debian zfs-dkms package generated by alien doesn't call the prerm script (rpm's %preun) with an integer as first parameter, which results in the following warning when the package is uninstalled: "zfs-dkms.prerm: line 3: [: remove: integer expression expected" Modify the if-condition to avoid the warning.
