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.
Fixes: c055e3eae0f1 ("crypto: xor - use ktime for template benchmarking")
