tpm: tpm_tis: stop transmit if retries are exhausted

tpm_tis_send_main() will attempt to retry sending data TPM_RETRY times.
Currently, if those retries are exhausted, the driver will attempt to
call execute. The TPM will be in the wrong state, leading to the
operation simply timing out.

Instead, if there is still an error after retries are exhausted, return
that error immediately.
