Apply vendor fixes to the High Point drivers:

- Don't call xpt_free_path() in os_query_remove_device() and
always return TRUE.
- Update os_buildsgl() to support build logical SG table which
will be used by lower RAID module.
- Return CAM_SEL_TIMEOUTstatus for SCSIcommand failed as target
missing.

Fix a mistake made during the import of the driver. Previous versions of
HPT drivers would sometimes test the value of a preprocessor definition but
not always make sure that the definition existed in the first place, leading
to warnings on newer compilers. I blindly assumed the same with this driver,
and it turned out to be wrong and to enable some code that doesn't work.

Fix a symbol conflict between hptrr and hptmv
