bcache: Avoid nested function definition

Browse Source 
Fixes below error with clang:
../drivers/md/bcache/sysfs.c:759:3: error: function definition is not allowed here
                {       return *((uint16_t *) r) - *((uint16_t *) l); }
                ^
../drivers/md/bcache/sysfs.c:789:32: error: use of undeclared identifier 'cmp'
                sort(p, n, sizeof(uint16_t), cmp, NULL);
                                             ^
2 errors generated.

v2:
rename function to __bch_cache_cmp
