s3-loadparm: mark a few parameters as having P_BYTES type

this fixes a problem with "max xmit = 32K" resulting in a maximum SMB
transmit size of 32 bytes, which makes for some very interesting
network traces!

This is what was causing smbtorture to consume gigabytes of memory in
the rpc.schannel test
