[PATCH v2] drivers/tty/moxa.c: Fix spelling mistake in comment

[shanmukh.iyer@gmail.com]

From: Shanmukh Iyer <shanmukh.iyer@gmail.com>

Corrected some spelling and grammar in the comments, such as:
- Units (baud -> baud rate)
- Sentence flow
- typos

This is part of my first patch to get familiar with
the kernel's patch contribution workflow.
