Subject: url: silence MSVC warning
X-Git-Tag: curl-7_72_0~133

url: silence MSVC warning

Since commit f3d501dc678, if proxy support is disabled, MSVC warns:
url.c : warning C4701: potentially uninitialized local variable
'hostaddr' used
url.c : error C4703: potentially uninitialized local pointer variable
'hostaddr' used

That could actually only happen if both `conn->bits.proxy` and
`CURL_DISABLE_PROXY` were enabled.
Initialize it to NULL to silence the warning.

Closes https://github.com/curl/curl/pull/5638
