tpm: Replace WARN_ONCE() with dev_err_once() in tpm_tis_status()
stable inclusion from stable-5.10.50 commit 97cbddc8a2bc62fe27fd3ca7be52abf3c675a4a6 bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=97cbddc8a2bc62fe27fd3ca7be52abf3c675a4a6 -------------------------------- commit 0178f9d0 upstream. Do not tear down the system when getting invalid status from a TPM chip. This can happen when panic-on-warn is used. Instead, introduce TPM_TIS_INVALID_STATUS bitflag and use it to trigger once the error reporting per chip. In addition, print out the value of TPM_STS for improved forensics.
