Fix SBO bit in disassembly mask for ldrah on AArch64.

The disassembly mask for ldarh incorrectly didn't mask out bit 20 which
is part of the SBO part of the instruction and shouldn't be considered input.

This fixes the wrong bit fixing the disassembly of instructions to
ldarh and makes the behavior consistent.
