Modify xfs_trans_reserve_quota_nblks so that we can reserve data and realtime blocks from the dquot at the same time. This change has the theoretical side effect that for allocations to realtime files we will reserve from the dquot both the number of rtblocks being allocated and the number of bmbt blocks that might be needed to add the mapping. However, since the mount code disables quota if it finds a realtime device, this should not result in any behavior changes. Now that we've moved the inode creation callers away from using the _nblks function, we can repurpose the (now unused) ninos argument for realtime blocks, so make that change. This also replaces the flags argument with a boolean parameter to force the reservation since we don't need to distinguish between data and rt quota reservations any more, and the only flag being passed in was FORCE_RES.

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.
