[PATCH] arch: cris: mm: add a code block for variable declaration

[Chen Gang]

Need a code block for variable declaration, or can not pass compiling
by old C compiler.

The new C compiler will report the warning (with allmodconfig):

  arch/cris/mm/fault.c: In function ‘do_page_fault’:
  arch/cris/mm/fault.c:228:3: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement]
