[PATCH v2] tpm: restore timeout for key creation commands

[Baoli Zhang <baoli.zhang@linux.intel.com>]

From: "Baoli Zhang" <baoli.zhang@linux.intel.com>

Commit 207696b17f38 ("tpm: use a map for tpm2_calc_ordinal_duration()")
inadvertently reduced the timeout for TPM2 key creation commands
(`CREATE_PRIMARY`, `CREATE`, `CREATE_LOADED`) from 300 seconds to 30
seconds.

This causes intermittent timeout failures, with several failures observed
across hundreds of test runs on some Intel platforms using Infineon
SLB9670 and SLB9672 TPM modules. Restore the timeout to 300 seconds to
avoid spurious failures.
