ext4_utils: Yet another MMC discard pain in the ass

 * Secure discard on this device is painfully slow. Use regular
   discard until the issue is sorted out.

Avoid underflow on an unsigned int when computering bg overrun

A computation for when a block group overruns the end of an image
was consistently storing a negative number in an unsigned var,
and then checking for >0, which is always true for negative numbers.
So first check if the number will be positive before computing it.

libpagemap: fix memory leak in pm_process_destroy()

procrank/librank not impacted because they end quickly. But other
programs that use libpagemap and last for long time can easily see this
memory leak.

procmem: Use size_t instead of int to remove a potential bug.

In procmem.c, num_maps and num_pages are declared as
int. Pointers (int*) to these variables are being
passed to functions pm_process_maps and pm_map_pagemap
respectively, both of which expect size_t * argument.

This will lead to problems in 64-bit systems where
size_t and int_t have different size.

To avoid the issue, num_maps and num_pages are declared
as size_t. In addition, loop counters i and j are now
declared as size_t to avoid comparison of signed int with
unsigned int.
