crypto: xor - Remove unused variable count in do_xor_speed
Clang warns: crypto/xor.c:101:4: warning: variable 'count' is uninitialized when used here [-Wuninitialized] count++; ^~~~~ crypto/xor.c:86:17: note: initialize the variable 'count' to silence this warning int i, j, count; ^ = 0 1 warning generated. After the refactoring to use ktime that happened in this function, count is only assigned, never read. Just remove the variable to get rid of the warning.
