Fix disassembly mask for vector sdot on AArch64.

This patch corrects the disassembly masks for by element dot product
instructions. The bit 10 was wrong and supposed to be 1.

This caused incorrect disassembly of instructions in the unallocated space to
disassemble as dot product instructions.

No encoding errors can arrise from this issue.
