[PATCH] riscv: Simplify base extension checks and direct boolean return

[Chin Yik Ming <yikming2222@gmail.com>]

Reduce three lines checking to single line using a ternary conditional
expression for getting the base extension word. In addition, the
test_bit macro function already return a boolean which matches the
return type of the caller, so directly return the result of the test_bit
macro function.
