4.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Mahesh Rajashekhara <mahesh.rajashekhara@microsemi.com>

commit 505aa4b6a8834a2300971c5220c380c3271ebde3 upstream.

A drive being sanitized will return NOT READY / ASC 0x4 / ASCQ
0x1b ("LOGICAL UNIT NOT READY. SANITIZE IN PROGRESS").

Prevent spinning up the drive until this condition clears.

[mkp: tweaked commit message]
