[PATCH] MIPS: fix tc_id calculation

[roy.qing.li@gmail.com]

From: RongQing.Li <roy.qing.li@gmail.com>

Now the tc_id is:
  (read_c0_tcbind() >> TCBIND_CURTC_SHIFT) & TCBIND_CURTC;
After substitute macro:
  (read_c0_tcbind() >> 21) & ((0xff) << 21)
It should be:
  (read_c0_tcbind() & ((0xff)<< 21)) >>21
