qcacmn: Allocate memory for fisa pkt history separately

Fisa packet history is around 6KB for each sw fisa
flow entry and this is part of the dp_fisa_rx_sw_ft
structure. The total size of the SW FT as a result is
around 830KB and the higher order memory allocation via
kzalloc for this could fail in low/fragmented memory
scenarios.

Fix is to allocate memory for FISA pkt history separately
and attach it to the SW FT entry.
