random: move random_min_urandom_seed into CONFIG_SYSCTL ifdef block
Building arm allnodefconfig causes the following build warning: drivers/char/random.c:318:12: warning: 'random_min_urandom_seed' defined but not used [-Wunused-variable] Fix the warning by moving 'random_min_urandom_seed' declaration inside the CONFIG_SYSCTL ifdef block, where it is actually used. While at it, remove the comment prior to the variable declaration. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
