Subject: [PATCH v2] f2fs: use kfree() instead of kvfree() to free superblock data

Use kfree() instead of kvfree() to free super in read_raw_super_block()
because the memory is allocated with kzalloc() in the function.
Use kfree() instead of kvfree() to free sbi in f2fs_fill_super() and
f2fs_put_super() because the memory is allocated with kzalloc().

Fixes: 5222595d093e ("f2fs: use kvmalloc, if kmalloc is failed")
Signed-off-by: Denis Efremov <efremov@...ux.com>

Changes in v2:
 - Single patch instead of two separate patches
 - kvfree fixed in f2fs_put_super
