Subject: [58/66] [SCSI] pmcraid: remove duplicate struct member

2.6.36-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Anil Ravindranath <anil_ravindranath@...-sierra.com>

commit df30e5059681ed0671c9cc6ff702fe9ca7f20042 upstream.

sense_buffer is both a direct member of struct pmcraid_cmd as well as
an indirect one via an anonymous union and struct.  Fix this clash by
eliminating the direct member in favour of the anonymous struct/union
one.  The name duplication apparently isn't noticed by gcc versions
earlier than 4.4
