btrfs: don't skip accounting in early ENOTTY return in btrfs_uring_encoded_read()

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.
