[PATCH v2 09/22] scripts/get_abi.pl: fix parse issues with some files

[Mauro Carvalho Chehab <mchehab+samsung@kernel.org>]

A few files are failing to parse:

	Documentation/ABI/testing/sysfs-bus-pci-devices-aer_stats
	Documentation/ABI/testing/sysfs-class-pktcdvd
	Documentation/ABI/testing/sysfs-bus-nfit

On all three files, the problem is that there is a ":" character
at the initial file description.

Improve the parse in order to handle those special cases.
