Subject: [PATCH 07/29] bus: mhi: core: Remove unnecessary counter from mhi_firmware_copy()

From: Bhaumik Bhatt <bbhatt@...eaurora.org>

There is an extra 'i' counter in the mhi_firmware_copy() function
which is unused. Remove it to clean-up code and reduce stack
space as well as improve efficiency of the function.

Fixes: cd457afb1667 ("bus: mhi: core: Add support for downloading firmware over BHIe")
