geo-rep: Handle ERANGE error during listxattr

llistxattr in Geo-rep is two syscall instead of one

SIZE = llistxattr(PATH, &BUF, 0);
BUF = create_buf(SIZE);
_ = llistxattr(PATH, &BUF, SIZE);

So if any new xattrs added just after first call by any other worker,
second syscall will fail with ERANGE error.

Now Geo-rep sends BUF with large size(256*100) and gets value
with only one syscall. Raises OSError if fails with ERANGE error
even after sending large BUF.
