atm: idt77252: Fix set-but-unused variables.
Two cases here: 1) idt77252_rx_raw() really does not make any use of the extracted PTI field of the atm header. 2) idt77252_collect_stat() only uses the register values in code which has been compiled out by a "NOTDEF" cpp test for more than 10 years. Just kill this NOTDEF code entirely, but keep the register reads in case they have side effects. Signed-off-by: David S. Miller <davem@davemloft.net>
