Jarkko Sakkinen 86b9820395 tpm: tpm_vtpm_proxy: fix a race condition in /dev/vtpmx creation 
commit f4032d615f90970d6c3ac1d9c0bce3351eb4445c upstream.

/dev/vtpmx is made visible before 'workqueue' is initialized, which can
lead to a memory corruption in the worst case scenario.

Address this by initializing 'workqueue' as the very first step of the
driver initialization.
