Subject: Fix warnings: ops.c: do_join(): Nonnull violation: FP.

Problem: Argument with 'nonnull' attribute passed null @ 3540.
         http://neovim.org/doc/reports/clang/report-fc14e0.html#EndPath.

Diagnostic: False potitive.
Rationale : `count` should be >= 2 by function precondition.
Resolution: Assert precondition.
