[PATCH] init/main.c: fix sparse warnings: context imbalance

[Hannes Eder <hannes@hanneseder.net>]

Impact: Attribute function 'init_post' with __releases(...).

Fix this sparse warnings:
  init/main.c:805:21: warning: context imbalance in 'init_post' - unexpected unlock
  init/main.c:899:9: warning: context imbalance in 'kernel_init' - wrong count at exit
