Fix that matching { and } can be searched in inter mode decision

Because #if ... #else ... put the '{' on the same line, dangling { or } occurs,
which causes automatic syntax analyzer, such as 'Ctrl-Shifht-P' in Eclipse
or '%' of vi, fail to find matching { and }.

For some developers, this can make quick reading and/or understaning blocks of code
almost impossible.

Three function or blocks are repaird.
1. av1_rd_pick_inter_mode_sb() {...}

2. for (midx = 0; midx < MAX_MODES; ++midx) {...}
   in av1_rd_pick_inter_mode_sb()

3. handle_inter_mode() {...}
