[PATCH ARM-Embedded-4_7-branch] fixing incoorect instruction length in checkin r193980

[Bin Cheng]

Hi,
On ARM-Embedded-4_7 branch, check-in(r193980) causes a "branch out of range"
bug. Root cause is the incorrect instruction length set by that check-in.
Since the length of instruction should strictly reflect the pattern it
matches, this patch fixes it by correcting the length.

Patch applied to ARM-Embedded-4_7-branch as r196368.

Thanks.
