cb39459fa8 sgv_pool_create(): Return NULL if sgv_pool_init() fails 
The current implementation of sgv_pool_create() returns a dangling
pointer if pool allocation succeeds but sgv_pool_init() fails. Modify
sgv_pool_create() such that a NULL pointer is returned if that happens.
This was detected by Coverity.

bd7c893f04 Multiple makefiles: autodetect SCST include directory 
It is cumbersome to change SCST_INC_DIR and SCST_DIR in each Makefile
before and after a release. Hence modify the Makefiles such that these
paths are detected automatically.

9226ba652c scst, SCSI pass-through: Do not complain unnecessarily about max_hw_sectors 
cmd->bufflen is in bytes so it has to be divided by the sector size before
being compared with queue_max_hw_sectors(). Other changes included in this
patch:
* Print the "rc" error code as a signed integer instead of as an unsigned
  hex number.
* Change "(int)rc" into "rc". The cast isn't necessary because rc has type
  int.
* Insert a "0x" prefix in front of the SCSI CDB opcode.

1f600fcc91 scst_local: Fix bug in error path 
device_unregister() invokes scst_local_release_adapter() and hence unregisters

session which would result in a crash.
