cpumask: statement expressions confuse some versions of gcc



when you take the address of the result.  Noticed on a sparc64 compile
using a version 3.4.5 cross compiler.

 kernel/time/tick-common.c: In function `tick_check_new_device':
 kernel/time/tick-common.c:210: error: invalid lvalue in unary `&'
 ...

Just make it a regular expression.
