Harshit Mogalapalli d36f6efbe0 module: Fix use-after-free bug in read_file_mod_stats() ...

Smatch warns:
	kernel/module/stats.c:394 read_file_mod_stats()
	warn: passing freed memory 'buf'

We are passing 'buf' to simple_read_from_buffer() after freeing it.

Fix this by changing the order of 'simple_read_from_buffer' and 'kfree'.
