[PORT FROM R2] mt9m114: mt9e013: add return value checking to prevent further processing when i2c err happens

BZ: 21906

ORIG-BZ: 19774

When condition mt9m114_MAX_WRITE_BUF_SIZE matched, the __mt9m114_buf_reg_array
called in mt9m114_write_reg_array doesn't use the return value to prevent
further processing in case of i2c transfer err happens. The same scenario exists
with mt9e013.

This patch adds the return value checking to resolve this issue.
