target: Reset data_length for COMPARE_AND_WRITE to NoLB * block_size
This patch resets se_cmd->data_length for COMPARE_AND_WRITE emulation
within sbc_compare_and_write() to NoLB * block_size in order to address
a bug with FILEIO backends where a I/O failure will occur when data_length
does not match the I/O size being actually dispatched for the individual
per block READs + WRITEs.
This is done late enough in sbc_compare_and_write() after the memory
allocations have occured in transport_generic_new_cmd() to not cause
any unwanted side-effects.
