Fix MAX_STACK_ENTRIES from 100 to 32

[wardenjohn]

Thanks for reading my suggestion. I found that the array for task stack entries when
doing livepatch function check is too large which seems to be unnecessary. Therefore,
I suggest to fix the MAX_STACK_ENTRIES from 100 to 32.

The patch is as follows:

Subject: [PATCH] Fix MAX_STACK_ENTRIES to 32

When checking the task stack, using an stack array of size 100 
seems to be to large for a task stack. Therefore, I suggest to
change the stack size from 100 to 32.
