[PATCH v3 2/6] target/riscv: Check for async flag in case of RISCV_EXCP_SEMIHOST.

[Rajnesh Kanwal]

RISCV_EXCP_SEMIHOST is set to 0x10, which can be a local interrupt id
as well. This change moves RISCV_EXCP_SEMIHOST to switch case so that
async flag check is performed before invoking semihosting logic.
