    zfs: Avoid a gcc -Wint-to-pointer-cast warning
    
    On 32-bit platforms long long is generally 64-bits.  Sufficiently modern
    versions of gcc (13 in my testing) complains when casting a pointer to
    an integer of a different width so cast to uintptr_t first to avoid the
    warning.
    
    Fix i386 gcc builds while we wait for this to be merged to OpenZFS.
