lib/iscsi: Remove inclusion of SPDK event library except shared memory ID for iSCSI top application

iSCSI library still needs to include SPDK event library only for
shared memory ID to allocate shared memory for iSCSI top application.

We will move the code to module library separately later but remove
all other inclusion of SPDK event library in this patch.
