Remove progress property support from encrypt_inplace()

Now that FDE support has been removed, encrypt_inplace() is only used by
metadata encryption, which passes false for the set_progress_properties
parameter.  Therefore, remove the set_progress_properties parameter and
the associated code to update the "vold.encrypt_inplace" and
"vold.encrypt_time_remaining" system properties.

Note that encrypt_inplace() still keeps track of its progress to some
extent, for the purpose of printing log messages; that hasn't changed.
