[R4R]fix deadlock on miner module when failed to commit trie

[unclezoro]

Description

A possible deadlock when commit trie failed

Rationale

A node stuck and failed to import any blocks, the go routine profile is: routine.txt

github.com/ethereum/go-ethereum/core/state.(*StateDB).Commit.func1.1(0x40eefc8fc0, 0x0, 0x420496c2f8, 0x1, 0x1, 0x572e056600a67eff, 0x99b123d0825edb78)
	/ext-go/1/src/github.com/ethereum/go-ethereum/core/state/statedb.go:1367 +0x2d4
github.com/ethereum/go-ethereum/core/state.(*StateDB).Commit.func1(0x0, 0x0)
	/ext-go/1/src/github.com/ethereum/go-ethereum/core/state/statedb.go:1413 +0x5c

Blocked in sending task to tasks channel.

The task itself will send response to taskResults, if CommitTrie failed, taskResults will get two signal, while the size of taskResults is len(s.stateObjectsDirty), which will cause the routine blocked.
