virNWFilterSnoopLeaseFileLoad: Don't typecast 'ipl.timeout'

Browse Source 
Use a temporary variable to avoid memory alignment issues on ARM:

../src/nwfilter/nwfilter_dhcpsnoop.c: In function ‘virNWFilterSnoopLeaseFileLoad’:
../src/nwfilter/nwfilter_dhcpsnoop.c:1745:20: error: cast increases required alignment of target type [-Werror=cast-align]
 1745 |                    (unsigned long long *) &ipl.timeout,
      |
