grep: fix leaking grep pattern

When creating a pattern via `create_grep_pat()` we allocate the pattern
member of the structure regardless of the token type. But later, when we
try to free the structure, we free the pattern member conditionally on
the token type and thus leak memory.

Plug this leak. The leak is exposed by t7814, but plugging it alone does
not make the whole test suite pass.
