btrfs_uring_encoded_read() returns early with -ENOTTY if the uring_cmd
is issued with IO_URING_F_COMPAT but the kernel doesn't support compat
syscalls. However, this early return bypasses the syscall accounting.
Go to out_acct instead to ensure the syscall is counted.
Fixes: 34310c442e ("btrfs: add io_uring command for encoded reads (ENCODED_READ ioctl)")

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 reStructuredText 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.
