Subject: [41/98] [SCSI] libfc: fix typo in retry check on received PRLI

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

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

From: Joe Eykholt <jeykholt@...co.com>

commit 85b5893ca97c69e409ecbb5ee90a5d99882369c4 upstream.

A received Fibre Channel ELS PRLI request contains a bit that
indicates whether the remote port supports certain retry processing
sequences.  The test for this bit was somehow coded to use multiply
instead of AND!

This case would apply only for target mode operation, and it is
unlikely to be noticed as an initiator.
