devtools: enhance error message in get maintainer script

Browse Source 
When the DPDK_GETMAINTAINER_PATH variable was not set, the error
message from get-maintainer.sh was quite cheap:

	$ devtools/get-maintainer.sh --help
	usage: get-maintainer.sh <patch>
	Cannot execute DPDK_GETMAINTAINER_PATH

Add a more detailed explanation about this variable in the help.

The DPDK_GETMAINTAINER_PATH variable should be set to the full path to
the get_maintainer.pl script located in Linux kernel sources. Example:
DPDK_GETMAINTAINER_PATH=~/linux/scripts/get_maintainer.pl
Also refer to devtools/load-devel-config to store your configuration.
