CVE-2021-47056

crypto: qat - ADF_STATUS_PF_RUNNING should be set after adf_dev_init

In the Linux kernel, the following vulnerability has been resolved:

crypto: qat - ADF_STATUS_PF_RUNNING should be set after adf_dev_init

ADF_STATUS_PF_RUNNING is (only) used and checked by adf_vf2pf_shutdown()
before calling adf_iov_putmsg()->mutex_lock(vf2pf_lock), however the
vf2pf_lock is initialized in adf_dev_init(), which can fail and when it
fail, the vf2pf_lock is either not initialized or destroyed, a subsequent
use of vf2pf_lock will cause issue.
To fix this issue, only set this flag if adf_dev_init() returns 0.
