[CIFS] Fix spurious reconnect on 2nd peek from read of SMB length

Browse Source 
When retrying kernel_recvmsg() because of a short read, check returned
length against the remaining length, not against total length. This
avoids unneeded session reconnects which would otherwise occur when
kernel_recvmsg() finally returns zero when asked to read zero bytes.
