Commit c6fc806247 ("staging:iio: ABI rework - add in_ or out_ prefix to
channnels") added the AD5868_CHANNEL macro to simplify channel initialization.
Unfortunately the macro hardcodes the channel's address to AD5686_ADDR_DAC0. As
a result writing to any of the channels will change the value of the first
channel.
This patch fixes the issue by calculating the channel address based on the
channel number.

Invoke cn_netlink_send() in a work context as opposed being called
in the context of channel callback. On entry into the channel callback
code the channel inbound spin lock is held and deferring to a work
context avoids having to invoke cn_netlink_send() while holding
the inbound lock. As part of this adjustment, also increase the
timeout value for waiting for the user level component of KVP.

The host gurantees that there can be only one kvp transaction active
against the guest. So, the transaction active state is needed only to
protect against spurious user level calls. The current code had a race
condition where the guest could prematurely return because the previous
transaction state was not cleared - this state was being cleared after
sending the response to the host and there was a window where the host
could notify the guest of a new transaction before the transaction active
state was properly set.
Also deal with the case when the user mode component
does not respond in a timely fashion correctly.
