ice_init_pkg_hints() clears hw->tnl before enumerating package labels,
but leaves hw->dvm_upd untouched. Every subsequent call to
ice_init_pkg() during reset recovery appends duplicate DVM and SVM boost
entries to hw->dvm_upd.tbl[] until hw->dvm_upd.count saturates at
ICE_DVM_MAX_ENTRIES (48).
During package download, ice_set_dvm_boost_entries() then issues a
redundant Update Package Admin Queue command for every accumulated
duplicate while holding the firmware Global Configuration Lock.
Zero hw->dvm_upd alongside hw->tnl before enumerating package hints.
