Update cp_irq_count_cached when reading messages rather than when writing a message to make sure the value is up to date and not stale from a previously handled CP_IRQ. AKE flow doesn't always respond to a read with a ACK write msg. E.g. AKE_Send_Pairing_Info will "timeout" because we received a CP_IRQ for reading AKE_Send_H_Prime but no write occurred between that and reading AKE_Send_Pairing_Info so cp_irq_count_cached is stale causing the wait to return right away rather than waiting for a new CP_IRQ.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
