    arm: Fix build following c/s 8e2aa76dc
    
    The ARM side of the cpu_nr_siblings() was missing a return type.  OSSTest
    reports:
    
      
/home/osstest/build.150502.build-arm64-xsm/xen/xen/include/asm/cpufeature.h:67:15:
      error: return type defaults to 'int' [-Werror=implicit-int]
       static inline cpu_nr_siblings(unsigned int)
                     ^~~~~~~~~~~~~~~
    
    My local build test then reported:
    
      /local/xen.git/xen/include/asm/cpufeature.h: In function 
â??cpu_nr_siblingsâ??:
      /local/xen.git/xen/include/asm/cpufeature.h:67:1: error: parameter name 
omitted
       static inline int cpu_nr_siblings(unsigned int)
        ^
    
    Fix it up to match its x86 counterpart.
