Stanislaw Gruszka c87dff8cc3 mt76: fix frag length allocation for usb
This is correct fix for c12128ce44 ("mt76: use a per rx queue page
fragment cache"). We use wrong length when we allocate segments for
MCU transmissions, which require bigger segment size than e->buf_size.

Commit 481bb04324 ("mt76: usb: make rx page_frag_cache access atomic")
partially solved the problem or actually mask it by changing
mt76u_mcu_init_rx() and mt76u_alloc_queues() sequence, so e->buf_size
become non zero any longer, but still not big enough to handle MCU data.

Patch fixes memory corruption which can manifest itself as random,
not easy to reproduce crashes, during mt76 driver load or unload.

README

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
