[ Upstream commit01542f651a] Commit88022d7201("blk-mq: don't handle failure in .get_budget") remove BLK_STS_RESOURCE return value and we only check if we can get the budget from .get_budget() now. Correct stale comment that ".get_budget() returns BLK_STS_NO_RESOURCE" to ".get_budget() fails to get the budget".

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.
