Yann Diorcet 4129e9ad6f tss2: Always init out buffer before calling tpm2_submit_command_real()

When tpm2_submit_command_real() is called for a retry, the content of
out buffer can already be set with previous tpm2_submit_command_real()
call's reply. Add a call to grub_tpm2_buffer_init() before tpm2_submit_command_real().

This solves the issues occurring during TPM_CC_Load command on the
integrated TPM 2.0 in Intel Elkhart Lake chip.
