[PATCH] soc: qcom: smem: fix checkpatch warnings

[Ramon Fried]

* Fixed checkpatch.sh warnings in smem.c & smem.h:
- WARNING: Prefer 'unsigned int' to bare use of 'unsigned'.
- WARNING: Block comments should align the * on each line.
- WARNING: line over 80 characters.
- ERROR: do not use assignment in if condition.

* Fixed grammar in comment.
