[SCSI] libfc: fix statistics for FCP input/output megabytes
The statistics for InputMegabytes and OutputMegabytes are
misnamed. They're accumulating bytes, not megabytes.
The statistic returned via /sys must be in megabytes, however,
which is what the HBA-API wants. The FCP code needs to accumulate
it in bytes and then divide by 1,000,000 (not 2^20) before it
presented via sysfs.
This affects fcoe.ko only, not fnic. The fnic driver
correctly by accumulating bytes and then converts to megabytes.
I checked that libhbalinux is using the /sys file directly without
conversion.
BTW, qla2xxx does divide by 2^20, which I'm not fixing here.
