While running a single stream UDPv6 test, we observed that amount
of CPU spent in NET_RX softirq was much greater than UDPv4 for an
equivalent receive rate. The test here was run on an ARM64 based
Android system. On further analysis with perf, we found that UDPv6
was spending significant time in the statistics netfilter targets
which did socket lookup per packet. These statistics rules perform
a lookup when there is no socket associated with the skb. Since
there are multiple instances of these rules based on UID, there
will be equal number of lookups per skb.
By introducing early demux for UDPv6, we avoid the redundant lookups.
This also helped to improve the performance (800Mbps -> 870Mbps) on a
CPU limited system in a single stream UDPv6 receive test with 1450
byte sized datagrams using iperf.

Explicitly clear the subsystem loading address in case of any
memory failure. It will help to avoid any platform dependency.

This patch move qmi handle destruction in a new function which is
executed in a worker thread and PD notification is issued in
blocking call. This avoid issue of late PD notification due to
delay in qmi handle destruction.

(cherry pick from commit 179448bfe4cd201e98e728391c6b01b25c849fe8)
This patch adds a max block check for get_data_block_bmap.
Trinity test program will send a block number as parameter into
ioctl_fibmap, which will be used in get_node_path(), when the block
number large than f2fs max blocks, it will trigger kernel bug.
