While processing of frames received before peer is registered in process
context, tcp_v4_rcv() is called which takes a spinlock and in between the
processing before spinlock can be released, it is getting preempted by
hif_napi_poll() as it gets executed in softirq context. It tries to take
the same spinlock in tcp_v4_rcv() resulting in deadlock.
Do netif_rx_ni() for frames received before peer is registered.

We have race condition between lro flush of hif_napi_poll and MC thread
lro flush while flushing the ol_txrx_cached_bufq packets for peer. Avoid
the situation by simply marking the all the Rx packets as LRO ineligible
while enqueuing packets to ol_rx_cached_buf.

On low memory conditions, qdf_mem_malloc_debug() fails and
on failure it triggers a host diag event to user space
which again tries to allocate memory using qdf_mem_malloc_debug()
which fails and this loop continues and might have caused
workqueue to get stuck.
Fix this by not sending the host diag event to user space on
low memory conditions.
