Fix mifare authentication for multiple blocks

Around line 1320 in rfid_asic_rc632.c the CRYPTO1 bit in the
RC632 is disabled. The RC632 docs state that this bit can only be set
by a successfull AUTHENT2 command, but may be cleared by the user to
disable encryption thereafter (but they don't say why anyone would want
to do that). (Henryk Ploetz)
