Do not lookup reverse dns with salt-ssh

[Ch3LL]

What does this PR do?

Salt-SSH was using the reverse DNS for the target. This PR ensures we do not check the reverse DNS and only use the target the user defined.

What issues does this PR fix or reference?

Fixes: #49840

Previous Behavior

salt-ssh target used the reverse DNS

(salt-py3.7)  ch3ll@thecakeisalie  ~/git/salt  ➦ 1e6bc974f7d  salt-ssh root@127.0.0.1 test.ping
localhost:
    True

As you can see we target 127.0.0.1 but it returns localhost as the target name

New Behavior

salt-ssh does not use reverse DNS and uses the target the user sets.

(salt-py3.7)  ch3ll@thecakeisalie  ~/git/salt   ssh_rev_dns  salt-ssh root@127.0.0.1 test.ping
127.0.0.1:
    True

the target stays the same (127.0.0.1)
