security: remove redundant assignment to return variable

Browse source 
In the case where rc is equal to EOPNOTSUPP it is being reassigned a
new value of zero that is never read. The following continue statement
loops back to the next iteration of the lsm_for_each_hook loop and
rc is being re-assigned a new value from the call to getselfattr.
The assignment is redundant and can be removed.
