So it need to check the pointer context before using it

If the kzalloc() fails then this code will crash. Return -ENOMEM instead.

There are two error code bugs here. The copy_to/from_user() functions
return the number of bytes remaining (a positive number). We should
return -EFAULT if the copy fails.
Second if we fail because "context.resp_status" is non-zero then return
-EINVAL instead of zero.

v1:
Add debugfs support to load/unload/invoke TA in runtime.
v2:
1. Update some variables to static.
2. Use PAGE_ALIGN to calculate shared buf size directly.
3. Remove fp check.
4. Update debugfs from read to write.
