ntfs: use direct pointer for inline data to avoid redundant allocation

Previously, NTFS used page allocation for IOMAP_INLINE to ensure that
the inline_data pointer was page-aligned, avoiding strict boundary checks
in the iomap core. Since the previous patch has removed the over-strict
PAGE_SIZE boundary check in iomap, NTFS can now safely point
iomap::inline_data directly to the MFT record.
This change eliminates redundant memory allocations and memcpy operations
in both read and write paths. It also simplifies the iomap_ops by removing
the need for a iomap_end callback that was previously used to free
the temporary page.
