[SCSI] bfa: BSG and User interface fixes. 

Made changes to set the rport maxfrsize param to use a value that is
equal to or less than the Buffer-to-Buffer Receive Data_Field size
specified in the Common Service Parameters.
Increased the diag memtest timeout for the Brocade-1860 adapters.
Made changes to enable valid port speed configuration check for all adapters.
Made changes to increase the max hw segments in a request, in order to
support larger data transfers from user space.
