Jonathan McDowell c84ceb546f tpm: Clean up TPM space after command failure 
[ Upstream commit e3aaebcbb7 ]

tpm_dev_transmit prepares the TPM space before attempting command
transmission. However if the command fails no rollback of this
preparation is done. This can result in transient handles being leaked
if the device is subsequently closed with no further commands performed.

Fix this by flushing the space in the event of command transmission
failure.

Fixes: 745b361e98 ("tpm: infrastructure for TPM spaces")
