x86/mm: Drop WARN from multi-BAR check
ioremapping multiple BARs produces a warning with a message "Your kernel is fine". This message mostly serves to comfort kernel developers. Users do not read the message, they only see the big scary warning which means something must be horribly broken with their system. Less dramatically, the warn also sets the taint flag which makes it difficult to differentiate problems. If the kernel is actually fine as the warning claims it doesn't make sense for it to be tainted. Change the WARN_ONCE to a pr_warn with the caller of the ioremap.
