pimd crashs while unconfigure of rp ka timer as we are trying to access
a yand dnode(suppress timer) which does not exist at the moment.
User just configured rp keepalive timer and not suppress timer,
the yang dnode would not be present. Instead of directly accessing
yang_dnode_get_unit16, first check the yang node exist using
the xpath.
Ticket: #3874971
Testing:
Before:
------
tor-11(config)# no ip pim rp keep-alive-timer 3000
vtysh: error reading from pimd: Success (0)Warning: closing connection to pimd because of an I/O error!

After:

INTRODUCTION
qpimd aims to implement a PIM (Protocol Independent Multicast)
daemon for the FRR Routing Suite.
qpimd implements PIM-SM (Sparse Mode) of RFC 4601.
Additionally MSDP has been implemented.
In order to deliver end-to-end multicast routing control
plane, qpimd includes the router-side of IGMPv[2|3] (RFC 3376).
