Adds a check to know if the asset is checked out to the logged in user to allow check the state in the view

[inietov]

Description

Requested assets should not still allow a user to "cancel" request if it's been checked out to them. So I added a validation and if the asset is already deployed to the logged in user the button appears deactivated. Not sure if this is correct or if it's best to put a label indicating that 'the asset is already deployed to you (logged user)'. Please tell me if you think there's a better approach.
