Scsi_cmnd is an unsuitable argument for eh_device_reset_handler(),
eh_target_reset_handler(), and eh_host_reset_handler() which do not have
the scope of one single SCSI command. These callbacks tend to use
fc_block_scsi_eh() requiring scsi_cmnd. In order to start decoupling
above eh callbacks from scsi_cmnd, introduce a new variant of the
function called fc_block_rport() taking an fc_rport as argument.
Refactor the old fc_block_scsi_eh() to simply delegate to
fc_block_rport().

It's better to use the DRIVER_ATTR_RW() and DRIVER_ATTR_RO() macros to
explicitly show that this is a read/write or read/only sysfs file. So
convert the remaining SCSI drivers that use the old style to use the
newer macros.
Bonus is that this removes some checkpatch.pl warnings :)
This is part of a series to drop DRIVER_ATTR() from the tree entirely.

When an IRQ arrives during PDMA transfer, pread() and pwrite() return
without waiting for the 53C80 registers to be ready and this ends up
messing up the chip state. This was observed with SONY CDU-55S which is
slow enough to disconnect during 4096-byte reads.
IRQ during PDMA is not an error so don't return -1. Instead, store the
remaining byte count for use by NCR5380_dma_residual().
