some problems in wss-v2.c

[Caiyujie007]

In function 'int loadidlemap()' , there are code:
unsigned long long *p;
while ((len = read(idlefd, p, IDLEMAP_CHUNK_SIZE)) > 0) {
p += IDLEMAP_CHUNK_SIZE;
g_idlebufsize += len;
}

I think the code should be 'p += 1' other than 'p += IDLEMAP_CHUNK_SIZE', because the datatype of p is unsigned long long. 'p += 1' means add point *p by 8 bytes.

Also, I think 'idlemapp = (pfn / 64) * BITMAP_CHUNK_SIZE;' at line 146 should be 'idlemapp = (pfn / 64)' because of the datetype of g_idlebuf is also 'unsigned long long'.

And 'g_idlebufsize += len;' at line 249 should be 'g_idlebufsize += 1;' for the same reason.

I modified the code and they works well.
