[ Upstream commit d2cc2f0b ]

A previous patch added a check if the firmware is too big, but it didn't
set the return error code with the right value.

[mchehab@osg.samsung.com: I ended by applying a v1 of Laura's patch, without
 the proper return code. This patch contains the difference between v2 and v1 of
 the Laura's "si2157: Bounds check firmware" patch]
