Change the regular expression string of the device type to support sIOV device of QAT

The string of the sIOV device type exceeds the range of [[alnum]], such as:
# adf_ctl status
Checking status of all devices.
There is 2 QAT acceleration device(s) in the system:
 qat_dev0 - type: vqat-adi,  inst_id: 0,  node_id: 0,  bsf: 0000:00:08.0,  #accel: 1 #engines: 1 state: up
 qat_dev1 - type: vqat-adi,  inst_id: 1,  node_id: 0,  bsf: 0000:00:09.0,  #accel: 1 #engines: 1 state: up
