Return on other errors at pkcs11_get_session
The `C_OpenSession` function can return several error codes, as seen in the open-source implementation of `pkcs11_api` in the OP-TEE client repository:
[OP-TEE optee_client - pkcs11_api.c#L278](https://github.com/OP-TEE/optee_client/blob/e79465eea85adc18a4075529ee20a16dfa263aea/libckteec/src/pkcs11_api.c#L278)
Some of these errors include:
- `CKR_CRYPTOKI_NOT_INITIALIZED`
- `CKR_DEVICE_ERROR`
- `CKR_DEVICE_MEMORY`
- `CKR_DEVICE_REMOVED`
- `CKR_FUNCTION_FAILED`
- `CKR_GENERAL_ERROR`
- `CKR_HOST_MEMORY`
- `CKR_SESSION_COUNT`
- `CKR_SESSION_PARALLEL_NOT_SUPPORTED`
- `CKR_SESSION_READ_WRITE_SO_EXISTS`
- `CKR_SLOT_ID_INVALID`
- `CKR_TOKEN_NOT_PRESENT`
- `CKR_TOKEN_NOT_RECOGNIZED`
- `CKR_TOKEN_WRITE_PROTECTED`
- `CKR_ARGUMENTS_BAD`
If any of these errors occur, the function currently does not return, causing it to be stuck at `pthread_cond_wait`, leading to a freeze in the caller process that uses the `libp11` API.
This commit ensures that when these errors are encountered, the function properly returns, preventing potential deadlocks.
