net: enetc: fix missing error code when pf->vf_state allocation fails
In enetc_pf_probe(), when the memory allocation for pf->vf_state fails,
the code jumps to the error handling label but the variable 'err' is not
assigned an appropriate error code beforehand. This causes the function
to return 0 (success) on an allocation failure path, misleading the
caller into thinking the probe succeeded. So set err to -ENOMEM before
jumping to the error handling label when the allocation for pf->vf_state
returns NULL.
Fixes: e15c5506dd39 ("net: enetc: allocate vf_state during PF probes")
