tee: change return code for REE FS supplicant cmd
If OP-TEE core is compiled with support of REE FS and RPMB
at the same time (CFG_RPMB_FS ?= y; CFG_RPMB_FS ?= y), and persistent
storage API is used with TEE_STORAGE_PRIVATE storage id, it will
lead to TA panic.
E/TC:? 0 TA panicked with code 0xffff0009
.....
E/TC:? 0 Call stack:
E/TC:? 0 0x000000004002f2f8 TEE_OpenPersistentObject at
lib/libutee/tee_api_objects.c:422
In this particular case TEE_ERROR_STORAGE_NOT_AVAILABLE is more suitable
than TEE_ERROR_NOT_IMPLEMENTED, as it provides to a TA a possibility
to handle this error code [1].
>From GPD TEE Internal Core specification [2]:
TEE_ERROR_STORAGE_NOT_AVAILABLE - if the persistent object is stored in a
storage area which is currently inaccessible. It may be associated with
the device but unplugged, busy, or inaccessible for some other reason.
