vim-patch:9.1.0458: Coverity complains about division by zero (#29149)

Browse Source 
Problem:  Coverity complains about division by zero
Solution: Check explicitly for sw_val being zero

Shouldn't happen, since tabstop value should always be larger than zero.
So just add this as a safety measure.
