[PATCH v2] keys: remove __user annotation from function prototype

[Randy Dunlap]

Remove a missed __user annotation from the prototype for
keyring_read(). This cures a sparse warning when it complains about
the difference in the prototype and the function definition.

security/keys/keyring.c:481:13: sparse:    long static [signed] [toplevel] keyring_read( ... )
security/keys/keyring.c:81:13: sparse:    long static [addressable] [signed] [toplevel] keyring_read( ... )

Fixes: 796e46f9e2cb ("keys: Remove outdated __user annotations").
