btrfs-progs: fix missing __error symbol in libbtrfs.so.0

Browse Source 
The easiest way to reproduce the error is to try to build
btrfs-progs with
    $ make LDFLAGS=-Wl,--no-undefined

    btrfs-list.o: In function `lookup_ino_path':
    btrfs-list.c:(.text+0x7d2): undefined reference to `__error'

Noticed by Denis Descheneaux when snapper tool
stopped working after upgrade to btrfs-progs-4.10.

As soname didn't change in 4.9 -> 4.10 release
I assume it's just an object file omission
in library depends and not the API/ABI change
of the library error printing.
