do_coredump: Do not take BKL
core_pattern is not actually protected and hasn't been ever since we introduced procfs support for sysctl -- a _long_ time. Don't take it here either. Also nothing inside do_coredump appears to require bkl protection. Signed-off-by: Arnd Bergmann <arnd@arndb.de> [ remove smp_lock.h headers ] Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>
