[dpdk-dev] [PATCH v4 23/38] net/ice/base: do not write TCAM entries back

[Qi Zhang <qi.z.zhang@intel.com>]

Profile TCAM entry removal is handled by the firmware when
freeing the resource, so the driver does not need to write these
default entries back with an update Package action.

This patch removes writing of the TCAM entry using Update Package
command when removing it, since the entry has already been freed
by firmware.
