mm/page_alloc.c: remove duplicate call to trace_mm_page_free_direct
trace_mm_page_free_direct() is called in function __free_pages(). But it
is called again in free_hot_page() if order == 0 and produce duplicate
records in trace file for mm_page_free_direct event. As below:
K-PID CPU# TIMESTAMP FUNCTION

gnome-terminal-1567 [000] 4415.255557: mm_page_free_direct: page=ffffea0003db9f40 pfn=1155800 order=0
gnome-terminal-1567 [000] 4415.255557: mm_page_free_direct: page=ffffea0003db9f40 pfn=1155800 order=0
This patch removes the first call and adds a call to
trace_mm_page_free_direct() in __free_pages_ok().
