fix: httpx fallbacks even though -nfs is given for dead hosts

[RamanaReddy0M]

--no-fallback-scheme is ignoring when using with ports switch

closes:

• wrong output message if used port switch #1092
• if host not exist, nfs is ignored if we use port switch  #1091

[tarunKoyalwar]

lgtm!

Before

$  echo https://123.google.com/ | httpx -duc -probe -sc -debug -nfs -ports 443
