ksmbd: decrease the number of SMB3 smbdirect server SGEs

The server-side SMBDirect layer requires no more than 6 send SGEs
The previous default of 8 causes ksmbd to fail on the SoftiWARP
(siw) provider, and possibly others. Additionally, large numbers
of SGEs reduces performance significantly on adapter implementations.
