The accelerator drivers supports users to enable VFs through the
module parameter 'vfs_num'. If the number of VFs to be enabled
exceeds the total VFs, all VFs are enabled. Change it to the same
as enabling VF through the 'sriov_numvfs' file. Returns -ERANGE
if the number of VFs to be enabled exceeds total VFs.
