[PATCH] ob-sql: blocks without :engine get stuck in org-edit-src-code on indent

[Ivan Sokolov]

user-error in sql-set-product interrupts normal execution flow in
org-indent-line for sql blocks without :engine.

Provided patch is not the best solution, but I do not have the time or
inclination to mess around with anything outside of the org-mode itself.
