[PATCH] tpm: tpm2-space: Skip handle check when context load returns -ENOENT

[Alper Ak]

When tpm2_load_context() returns -ENOENT, the session is marked as
forgotten by setting session_tbl[i] to 0. Although tpm2_load_context()
also sets handle to 0 in this case, the subsequent comparison
"handle != space->session_tbl[i]" (0 != 0) is always false and serves
no purpose.

Add continue to skip this unnecessary comparison when load fails with
-ENOENT, making the control flow clearer and fix possible
uninitialized 'handle' variable.

Fixes: 4d57856a21ed2 ("tpm2: add session handle context saving and restoring to 
the space code")
