Revert deadlock fix in ProcessGetData

Browse Source 
Fix was introdeced in:
https://github.com/dashpay/dash/pull/1169
A fix was later applied to fix a race condition:
https://github.com/dashpay/dash/pull/1178

This has to be reverted to be able to backport multiple changes from Bitcoin.
Later backported PRs from Bitcoin will remove cs_mapRelay and thus also
remove the deadlock that was initially fixed with the above PRs.
