VFS: Make pathwalk use d_is_reg() rather than S_ISREG()
Make pathwalk use d_is_reg() rather than S_ISREG() to determine whether to honour O_TRUNC. Since this occurs after complete_walk(), the dentry type field cannot change and the inode pointer cannot change as we hold a ref on the dentry, so this should be safe.
