[PATCH v1] tpm: restore timeout for key creation commands

After the per-command duration map was introduced, TPM2 key creation
commands (`CREATE_PRIMARY`, `CREATE`, `CREATE_LOADED`) were limited to
30 seconds.

On some platforms this is not sufficient and key creation can time out.
Commit 207696b17f38 ("tpm: use a map for tpm2_calc_ordinal_duration()")
inadvertently reduced these command timeouts from 300 seconds to 30
seconds. Restore them to 300 seconds to avoid spurious failures.

Fixes: 207696b17f38 ("tpm: use a map for tpm2_calc_ordinal_duration()")
