btrfs: remove btrfs_err_str function from uapi/linux/btrfs.h

btrfs_err_str function is not called from anywhere and is replicated
in the userspace headers for btrfs-progs.

It's removal also fixes the following linux/btrfs.h userspace
compilation error:

/usr/include/linux/btrfs.h: In function 'btrfs_err_str':
/usr/include/linux/btrfs.h:740:11: error: 'NULL' undeclared (first use in this function)
    return NULL;
