The function iterates an index from 0 to NUM_PMKID_CACHE and returns the first index for which the condition is true. If no such index is found, the function returns -1. Current code has a complex control flow that obfuscates this simple task. Replace it with a loop. Also, given the shortened function body, replace the long variable name psecuritypriv with a short variable name p.
