grep/pcre2: drop needless assignment to NULL

Remove a redundant assignment of pcre2_compile_context dating back to
my 94da9193a6e (grep: add support for PCRE v2, 2017-06-01).

In create_grep_pat() we xcalloc() the "grep_pat" struct, so there's no
need to NULL out individual members here.

I think this was probably something left over from an earlier
development version of mine.
