nilfs2: do not repair reserved inode bitmap in nilfs_new_inode()

After commit 93aef9e ("nilfs2: fix incorrect inode allocation from
reserved inodes") is applied, the inode number returned by
nilfs_ifile_create_inode() is guaranteed to always be greater than or
equal to NILFS_USER_INO, so if the inode number is a reserved inode number
(less than NILFS_USER_INO), the code to repair the bitmap immediately
following it is no longer executed.  So, delete it.
