As discussed in PR conversation¹, fix² of #38972 could make existing Foreman environment doesn't work if user sets both IP address and FQDN of target BMC.

Discussion with colleague concludes that priority of IP address & FQDN set by user should be changed to 'IP address -> FQDN' with following reason:

• If user specifies both IP address and FQDN, it's natural for IP address to take precedence. If user expects name resolution of FQDN through DNS, they may only specify FQDN. It's fair assumption that user expects IP address is used when user specifies IP address along with FQDN.

In addition to above reason, making IP address higher precedence over FQDN doesn't affect existing Foreman user environment.
