scsi: qla2xxx: Clarify MPI optrom address/length units

Browse source

The kdoc for qla29xx_mpi_optrom_data() described @offset as an "Offset into
the device memory", which reads like a byte address and invites confusion
with the per-chunk word-granular address advance in the transfer loop.

MBC_LOAD_DUMP_MPI_RAM is word-addressed: @offset is an MPI RAM address in
32-bit words, and @length is a byte count that is converted internally to a
word count. Document this to reflect the existing behavior. No functional
change.
