qcacmn: Avoid using small buffer address

The memory below 0x2000 is reserved for the target use,
so any memory in this region should not used by host.
But on some third-party platforms, we observe such
memory is allocated for RX buffer, which cause HW/FW
NOC error, then RX is stuck. To address this,
re-allocate RX buffers when small buffer appear.
