[PATCH] script: get_abi.pl: escape "<" and ">" characters

[Mauro Carvalho Chehab]

After merging the akpm-current tree, today's linux-next build (htmldocs)
produced this warning:

	Documentation/ABI/testing/sysfs-kernel-mm-cma:2: WARNING: Inline interpreted text or phrase reference start-string without end-string.

Introduced by commit 439d477342a3 ("mm: cma: support sysfs")

As pointed by Jonathan, the problem is this text in
sysfs-kernel-mm-cma:

	Each CMA heap subdirectory (that is, each
	/sys/kernel/mm/cma/<cma-heap-name> directory) contains the
	following items:

Is not parsed well, becase the major/minor signs need to be
escaped, when converted into cross-references.
