ice: Fix lldp packets dropping after changing the number of channels
[ Upstream commit 9debb703e14939dfafa5d403f27c4feb2e9f6501 ]
After vsi setup refactor commit 6624e780a577 ("ice: split ice_vsi_setup
into smaller functions") ice_cfg_sw_lldp function which removes rx rule
directing LLDP packets to vsi is moved from ice_vsi_release to
ice_vsi_decfg function. ice_vsi_decfg is used in more cases than just in
vsi_release resulting in unnecessary removal of rx lldp packets handling
switch rule. This leads to lldp packets being dropped after a change number
of channels via ethtool.
This patch moves ice_cfg_sw_lldp function that removes rx lldp sw rule back
to ice_vsi_release function.
