qcacld-3.0: Remove struct hdd_config::enable_fisa_lru_deletion

The following patch added logic to HDD to read the value of the
CFG_DP_RX_FISA_LRU_DEL_ENABLE configuration item and store it in
struct hdd_config:
  qcacld-3.0: Add ini to enable FISA LRU eviction
  Change-Id I9930ec260bcab5ba8c8f1e594dbfde35965dff2e

However, the datapath maintains this configuration item on its own, and
the copy maintained by HDD is not used, so remove that logic.

Change-Id: I970195cf199c33802db5f84eeea4f622306703cd
CRs-Fixed: 3424797
