[PATCH 1/1] [mm]: cma: change pr_info to pr_err for cma_alloc fail log

[Pintu Agarwal <pintu.ping@gmail.com>]

It was observed that under cma_alloc fail log, pr_info was
used instead of pr_err.
This will lead to problem if printk debug level is set to
below 7. In this case the cma_alloc failure log will not
be captured in the log and it will be difficult to debug.

Simply replace the pr_info with pr_err to capture failure log.
