rpc: change client insecure port ceiling from 65535 to 49151

current port allocation to various processes (clumsy):

 1023 - 1       -> client ports range if bind secure is turned on
49151 - 1024    -> fall back to this, if in above case ports exhaust
65535 - 1024    -> client port range if bind insecure is on
49152 - 65535   -> brick port range

now, we have segregated port ranges 0 - 65535 to below 3 ranges

 1023 - 1       -> client ports range if bind secure is turned on
49151 - 1024    -> client port range if bind insecure is on
                   (fall back to this, if in above case ports exhaust)
49152 - 65535   -> brick port range

so now we have a clean segregation of port mapping
