svn commit: r296890 - head/sys/dev/mfi

[Warner Losh]

Author: imp
Date: Tue Mar 15 04:56:39 2016
New Revision: 296890
URL: https://svnweb.freebsd.org/changeset/base/296890

Log:
  Remove bare & 0x3; it encodes the values of BIO_READ and
  BIO_WRITE. It's also unnecessary since the only cases in this switch
  are those two.
