Fix an erroneously copy/pasted check for the pcre2_jit_stack variable to check pcre2_match_context instead. The former was already checked in the preceding "if" statement.
This is a trivial and obvious error introduced in my commit 94da9193a6 ("grep: add support for PCRE v2", 2017-06-01).
In practice if pcre2_match_context_create() returned NULL we were likely in a situation where malloc() was returning NULL, and were thus screwed anyway, but if only the pcre2_match_context_create() call returned NULL (through some transitory bug) PCRE v2 would just allocate and supply its own context object when matching, and we'd run normally at the trivial expense of not getting a slight speedup by sharing the context object between successive matches.
