CephFS doesn't had a maximum xattr size. Instead, it imposes a maximum size
for the full set of xattrs names+values, which by default is 64K but may be
changed.
Test generic/486 started to fail after fixing a ceph bug where this limit
wasn't being imposed. Adjust dynamically the size of the xattr being set
if the error returned is -ENOSPC.
