[PATCH v3 3/7] trace2: remove dead code in maybe_add_string_va()

["Jeff Hostetler via GitGitGadget" <gitgitgadget@gmail.com>]

From: Jeff Hostetler <jeffhost@microsoft.com>

Remove an unnecessary "if" block in maybe_add_string_va().

Commit "ad006fe419e trace2: NULL is not allowed for va_list"
changed "if (fmt && *fmt && ap)" to just "if (fmt && *fmt)"
because it isn't safe to treat 'ap' as a pointer.  This made
the "if" block following it unnecessary.
