ext4: propagate flags to convert_initialized_extent()
Currently, ext4_zero_range passes EXT4_EX_NOCACHE flag to avoid caching
extents however this is not respected by convert_initialized_extent().
Hence, modify it to accept flags from the caller and to pass the flags
on to other extent manipulation functions it calls. This makes
sure the NOCACHE flag is respected throughout the code path.
Also, we no longer explicitly pass CONVERT_UNWRITTEN as the caller takes
care of this.
