94fbc49091 Fix qla2x00t compilation warnings on RHEL 6.1 
The attached patch fixes compilation warnings for the qla2x00t driver
when compiled by RHEL 6.1, kernel version 2.6.32-131.0.15.el6. I
believe this is the second kernel version for RHEL 6.1.

95246ee9d7 scstadmin: Make _syswrite() translate EBUSY into "writing failed" 
_syswrite() callers check whether writing into an SCST sysfs attribute
succeeded by checking whether the value returned by this function is
defined(). Return undef (failed) instead of -1 (success) if syswrite()
returned error code EBUSY (found this through source reading). Return
$length instead of length($cmd) if the initial write triggered EAGAIN.
Remove a superfluous $bytes = undef statement. Eliminate the variable
$wait.

39e304dc76 scst: Don't suspend activity during removal of a SCSI device 
SCST allows SCSI pass-through to SCSI devices registered with the SCSI
initiator core. SCST I/O activity has to be suspended before a LUN
that corresponds to such a SCSI device can be removed safely. Do not
suspend I/O when a SCSI device is being removed that has not been
exported as an SCST LUN such that removal of such devices does not
slow down I/O.

b25cb2a7e5 scst: Fix MAINTENANCE IN parsing 
Although I do not know of any initiator that asks for the extended
parameter data format when submitting a REPORT TARGET PORT GROUPS
command, I think it's a good idea to support that data format (i.e.
three most significant bits of the second CDB byte are 001 instead
of 000). The attached patch should implement that. Additionally,
cmd->op_name is set to something more descriptive than
"MAINTENANCE IN" in that patch.
