bgpd: sh running config is not considering values provided via -e for max-paths

bgpd: sh running config is not considering values provided via -e for max-paths

problem
1. run the bgp with -e1 option
2. c t
   router bgp 100
3. show running config
    !
     address-family ipv6 multicast
      maximum-paths 1
      maximum-paths ibgp 1
     exit-address-family
    !
address families should not dump maximum-paths if there
value is same as value provided at run time.

fix
if the maxpaths_ebgp value is same as multipath_num global
object, don't dump maximum-paths.
