tee: fix memory allocation failure checks on drv_data and amdtee

Browse Source 
Currently the memory allocation failure checks on drv_data and
amdtee are using IS_ERR rather than checking for a null pointer.
Fix these checks to use the conventional null pointer check.

Addresses-Coverity: ("Dereference null return")
Fixes: 757cc3e9ff ("tee: add AMD-TEE driver")
