369863f015 Allow install SCST in any location 
Currently the install location of SCST is pretty much hard coded into 
the Makefiles to be /usr/local.

I am custom building a system for ZFS & SCST and I want to install in 
/usr instead of /usr/local.

Currently I am doing a “find . -name Makefile -exec sed -i 's:/usr/local:/usr:g'
{} \;” to accommodate this.

This patch fixes it.

a0ee2a2396 qla2x00t: Clean up DMA address computation code 
The expression "sg_dma_address(prm->sg)" occurs several times in several
pieces of code that compute a DMA address. Make these pieces of code
somewhat easier to read by storing the DMA address in a temporary variable
called "dma_addr".

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.

c6d247254c scst_local: Remove a superfluous include path 
Target drivers must not include header files from the SCST source
code directory. Hence remove -I$(SCST_DIR) from the compiler flags.
