This fixes following assert failure.

 #3  0xb602ca8c in __GI___assert_fail (assertion=0xb4101520 "\001",
     assertion@entry=0x16cfd8 "client != NULL", file=file@entry=0x16ce5c "src/bin/core/e_view_client.c", line=line@entry=108, function=function@entry=0x16e044 <__PRETTY_FUNCTION__.52349> "e_view_client_view_get") at /usr/src/debug/glibc-2.30-3.14.arm/assert/assert.c:101

The function, _e_client_del() can be called without ec->frame if
creating ec->frame is failed.
