bus: mhi: core: Prevent sending multiple RDDM entry callbacks
If an mhi_power_down() is initiated after the device has entered RDDM and a status callback was provided for it, it is possible that another BHI interrupt fires while waiting for the MHI RESET to be cleared. If that happens, MHI host would have moved a "disabled" execution environment and the check to allow sending an RDDM status callback will pass when it is should not. Add a check to see if MHI is in an active state before proceeding.

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.
