fix: missing 'lttng_fs_info_fsid' wrapper in btrfs backport
    
    The following backported patch was missing the use of the
    'lttng_fs_info_fsid' wrapper to enable compatibility with upstream
    stable kernels.

            btrfs: use fs_info for btrfs_handle_em_exist tracepoint
    
            We really want to know to which filesystem the extent map events belong,
            but as it cannot be reached from the extent_map pointers, we need to
            pass it down the callchain.
