mt76_dma_rx_cleanup would be frequenetly called up to reset the dma rings to be freshed as new ones when switching back from the deep sleep mode to the active mode on mt7921 and mt7922. Shrink the scope of spin_lock_bh in mt76_dma_rx_cleanup being held up to allow the kernel scheduler to be able to switch other tasks in time by reducing the latency.

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.
