[PATCH 2/7] nilfs2: use nilfs_warning() in allocator implementation

[Ryusuke Konishi]

This uses nilfs_warning() to replace "printk(KERN_WARNING ...);" in
the bitmap based allocator implementation of nilfs2.  The warning
messages are modified to include the device name and the inode number
in each message.  This makes it clear which metadata file of which
device has output warnings such as "entry number xxxx already freed".
