grep: remove redundant double assignment to 0

Stop assigning 0 to the extended_regexp_option field right after we've
zeroed out the entire struct with memset() just a few lines earlier.

Unlike some of the code being refactored in subsequent commits, this
was always completely redundant. See the original code introduced in
84befcd0a4 ("grep: add a grep.patternType configuration setting",
2012-08-03).
