[PATCH 2/6] f2fs: move out f2fs_balance_fs from gc_thread_func

[Namjae Jeon <linkinjeon@gmail.com>]

From: Namjae Jeon <namjae.jeon@samsung.com>

When GC thread is running continously there is no need to call
f2fs_balance_fs unconditinally for garbage collection, instead
the garbage collection will be taken via. calling f2fs_gc in the
thread. So, we can move out the balance out of thread loop and
make it run initially when the thread is started.
