tpm: fix wrong return value in tpm_pcr_extend

BugLink: https://bugs.launchpad.net/bugs/1876361
commit 29cb79795e324a8b65e7891d76f8f6ca911ba440 upstream.

For the algorithm that does not match the bank, a positive
value EINVAL is returned here. I think this is a typo error.
It is necessary to return an error value.
