[PATCH] i2c: bcm2835: add missing braces to for loop in bcm2835_i2c_xfer

[zhaohaiyang1]

From: zhaohaiyang1 <zhaohaiyang1 at xiaomi.com>

Add curly braces around the multi-statement body of the for loop
that checks for unsupported read messages. This fixes a coding
style issue where the compound statement lacked explicit braces.
