Drop an assignment added in b65abcafc7a (grep: use PCRE v2 for
optimized fixed-string search, 2019-07-01) and the overly cautious
assert() I added in 94da9193a6e (grep: add support for PCRE v2,

There was never a good reason for this, it's just a relic from when I
initially wrote the PCREv2 support. We're not going to have confusion
about compile_pcre2_pattern() being called when it shouldn't just
because we forgot to cargo-cult this opt->pcre2 option, and "opt"
is (mostly) used for the options the user supplied, let's avoid the
pattern of needlessly assigning to it.

With my in-flight removal of PCREv1 [1] ("Remove support for v1 of the
PCRE library", 2021-01-24) there'll be even less confusion around what
we call where in these codepaths, which is one more reason to remove
