[MIPS] Fix BUG(), BUG_ON() handling
With commit 63dc68a8cf60cb110b147dab1704d990808b39e2, kernel can not handle BUG() and BUG_ON() properly since get_user() returns false for kernel code. Use __get_user() to skip unnecessary access_ok(). This patch also make BRK_BUG code encoded in the TNE instruction.
