LU-4688 mdt: remove export_put() from mdt_export_evict()

This export reference dropping is not needed here, export
referenced from ptlrpc level and will be dropped there as
well. It looks like that call to the class_export_put()
was added just similar to other places where the
class_fail_export() is called but in those cases export
reference was taken right in the same function while here
it is taken by external caller and will dropped there.
