Replace some u.Printf calls with u.Errorf in handlers.go

[Marcool04]

Hi there,

I was hit with an error today that stated:

handlers.go:197: Extraction Error: blabla.rar: os.MkdirAll: mkdir /home/transmission/Lidarr/lidarr/blabla.rar_unpackerred: permission denied

except that this showed with an [INFO] priority level, and so I missed it for a while before reading through again.

I took the liberty of making this simple change so that message (and one other I feel is an error rather than an "INFO") will be printed as such.

Thanks for taking this into consideration.

Regards
Mark

Thanks for taking the time to contribute. I agree the INFO you got should say ERROR.
