f2fs: cleanup trace event of f2fs_submit_page_{m,}bio with DECLARE_EVENT_CLASS

Browse Source 
This patch adds missing parameter _type_ for trace_f2fs_submit_page_bio, then
use DECLARE_EVENT_CLASS/DEFINE_EVENT_CONDITION pair to cleanup some trace event
code related to f2fs_submit_page_{m,}bio.

Additionally, after we remove redundant code, size of code can be reduced:
   text    data     bss     dec     hex filename
