Remove redundant assignment in CreateWorkExprContext

[Chao Li]

Hi,

While discussing [1], I was reading execUtils.c, then I noticed this 
redundant local variable assignment in CreateWorkExprContext(). The 
attached patch fixed that.

Subject: [PATCH v1] Remove redundant assignemnt in CreateWorkExprContext

In CreateWorkExprContext(), maxBlockSize is initialized to
ALLOCSET_DEFAULT_MAXSIZE, and it then immediately reassigned,
thus the initialization is a redundant.
