[PATCH v3 2/3] firmware_loader: fix positive return value being treat as error return

["Kweh, Hock Leong" <hock.leong.kweh@intel.com>]

From: "Kweh, Hock Leong" <hock.leong.kweh@intel.com>

Due to wait_for_completion_interruptible_timeout() will return
its remaining timeout jiffies value if timeout does not happen,
the error check code "if (ret)" will treat that as error return.
So, fixing the issue by re-assigning back a 'Zero' to the return
value when the wait is completed without timeout.
