net/rds: Fix 'ib_evt_handler_call' element in 'rds_ib_stat_names'

[ Upstream commit 05a82481a3024b94db00b8c816bb3d526b5209e0 ]

All entries in 'rds_ib_stat_names' are stringified versions
of the corresponding "struct rds_ib_statistics" element
without the "s_"-prefix.

Fix entry 'ib_evt_handler_call' to do the same.
