[Replicant] Fix more typos

[Denis 'GNUtoo' Carikli]

Hi,

Here are fixes for 4 more typos that I found after sending the first
patch.

In addition to the patches that will follow in a response to
this mail, here's an URL to the see the patch in a web interface:
https://git.replicant.us//contrib/GNUtoo/hardware_replicant_libsamsung-ipc/commit/?id=82c1658cf5e3daac8aae73776235c4ca91d2f0e4

And here's how to get it in a git repository:
git clone https://git.replicant.us//GNUtoo/hardware_replicant_libsamsung-ipc
cd hardware_replicant_libsamsung-ipc
git show 82c1658cf5e3daac8aae73776235c4ca91d2f0e4
