Subject: Fix warnings: regexp.c: match_with_backref(): Nonnull violation: FP.

Problem: Argument with 'nonnull' attribute passed null @ 5632.
         http://neovim.org/doc/reports/clang/report-041a0e.html#EndPath.

Diagnostic: False positive.
Rationale : `p = reg_getline(clnum)` above should not be null, because
            `clnum` starts at `start_lnum` and only increments after
            that.
Resolution: Assert p not null.
