ntfs: fix variable dereferenced before check ni and attr in ntfs_attrlist_entry_add()

Browse Source 
Smatch warnings:

ntfs_attrlist_entry_add() warn: variable dereferenced before check 'ni'
ntfs_attrlist_entry_add() warn: variable dereferenced before check 'attr'

Moves the ntfs_debug() call after the NULL pointer checks to ensure safe
access to the structure members.
