Jit-lock error because of missing quote in adoc-kw-verbatim-paragraph-sequence

[TobiasZawada]

I get the following error message because of a missing quote before adoc-reserved in adoc-kw-verbatim-paragraph-sequence:

(jit-lock--run-functions 10093 11074) [UNPR HOST test.adoc]: Symbol’s value as variable is void: adoc-reserved

Note, that this is an obvious error with a simple fix.
The pull request should not pose any problems.
