Fix warnings: regexp.c: br_regcomp(): Np dereference: MI.

Problem: Dereference of null pointer @ 1312.
         http://neovim.org/doc/reports/clang/report-b1d09a.html#EndPath

Diagnostic: Multithreading issue.
Rationale : Suggested error path contains two succesive calls to
            `regnext(scan)`, first of which returning nonnull, the
            second one returning null. This can only occur if global
            `reg_toolong` accesed in `regnext()` changes between the
            calls.
Resolution: Use local variable to cache first `regnext(scan)` result.
            Note that this change alters function semantics, as now
            function only issues one call instead of two, reusing the
            result for the second time.
            This shouldn't be a problem, though, as new semantics should
            be in fact be better.
