Did Slave Leia view Jabba as her master?

Probably not. She probably viewed him as someone who was keeping her just for entertainment and she was mostly concerned on how to get out of his grasp.

However, consider this. On the Sail Barge, en route to the would-be execution of her friends, Leia was standing some 6+ feet away from Jabba's throne, when he yanked her chain. At first she gave him a defiant glare (further confirming the above theory), but when Jabba tugged again, Leia was pulled back from the window.

What we see in the film appears to be her "being pulled close" to him; however, slowing it down to frame-by-frame glances, we can see that Leia had to turn around, run to the throne, jump up onto it, straighten up before Jabba, and subsequently press her lower body up against his belly before leaning in...and only then does she turn her head away.

This suggests that she knew how to respond to Jabba's chain-yanking, making an automatic reaction of coming to him and pressing up close; she was too far away to be simply "pulled to" him. This active response would indicate that she had become accustomed to Jabba's advances, furthering the possibility that perhaps, yes, she DID view him as her superior...or, as the question phrased it, her "Master."
