fix: resolve panic when adding list entry before existing one (#1379)

The getDeletedItems (RESTCONF) and addDeletedItemsXML (NETCONF) template
functions had swapped loop indices when comparing list-type attributes
within list entries. When i iterates state and j is the matched index in
data, the code incorrectly read data[i] and state[j], causing an
index-out-of-range panic whenever j > len(state)-1 (i.e., a new entry
is inserted before an existing one).

Fixed at both nesting levels in both functions (4 sites total in
gen/templates/model.go). Affects iosxe_route_map, iosxe_crypto_pki,
iosxe_radius_server, and iosxe_system generated models.
