Taras Kondratiuk a6889df540 mmc: block: fix packed command header endianness 
commit f68381a70b upstream.

The code that fills packed command header assumes that CPU runs in
little-endian mode. Hence the header is malformed in big-endian mode
and causes MMC data transfer errors:

[  563.200828] mmcblk0: error -110 transferring data, sector 2048, nr 8, cmd response 0x900, card status 0xc40
[  563.219647] mmcblk0: packed cmd failed, nr 2, sectors 16, failure index: -1

Convert header data to LE.
