I have encrypted my phone and now I want to set a normal swipe lock but I cannot enable it. How do I disable the encryption?

You will have to reformat your phone with PCC

Supposed if I have switched off my mobile and a person robs it. So when.he will switch on the phone will he be able to use the phone or he can factory rest the mobile without entering password?

That person can still perform this software repair that uliwooly mentioned earlier. But when a software repair is performed, all the data will be lost so they cannot access your data.

Sony should do something about this! 😕

You could use MyXperia or Android device manager to lock your phone.

How exactly is to "reformat" the phone? I only found an option called Software Repair and in the past this option just reflash the firmware but nothing else...

I have tried reflashing the .FTF using another software but still encryption is still there and this critically slow down the performance of the device, so I really wish to decrypt it...
