[PATCH][next] crypto: asymmetric_keys: remove redundant pointer secs

[Colin Ian King]

The pointer secs is being assigned a value however secs is never
read afterwards. The pointer secs is redundant and can be removed.

Cleans up clang scan build warning:
warning: Although the value stored to 'secs' is used in the enclosing
expression, the value is never actually read from 'secs'
[deadcode.DeadStores]
