scsi: devinfo: Add BLIST_NO_RSOC for Promise VTrak E310f

The extremely slow boots reported July 2014 in bug 79901:

  https://bugzilla.kernel.org/show_bug.cgi?id=79901

for Promise VTrak E610f 3U 16-bay FC RAID enclosure occur also with the
Promise VTrak E310f 2U 12-bay FC RAID enclosure. The 2014 patch:

  https://bugzilla.kernel.org/attachment.cgi?id=144101&action=diff

added support for the BLIST_NO_RSOC flag and specified that flag for the
Promise VTrak E610f. This current patch simply adds the E310f to that
same list.

One curiosity is the additional BLIST_SPARSELUN flag. This was also in
the 2014 patch for the E610f, and was already in place for *all* Promise
devices since 2007 due to commit e0b2e597d5dd ("[SCSI] stex: fix id
mapping issue") which added the line:

  {"Promise", "", NULL, BLIST_SPARSELUN}

The 2007 commit message talks of issues with SuperTrak EX (stex) but the
added line did not limit itself to that particular device family.  The
current patch for E310F, like the 2014 patch for E610f, adds
BLIST_NO_RSOC while preserving BLIST_SPARSELUN from 2007.
