Next-branch fails on ARM Cortex-M double precision instructions

[daveb1]

Problem
Latest capstone next-branch fails ARM Cortex-M disassembly for ARM Cortex-M double precision instructions

cstool command line:
cstool -d -s cortexm "80 b4 00 af 0a 4b d3 ed 00 7a b7 ee e7 6a 9f ed 06 5b 85 ee 06 7b f7 ee c7 7b b0 ee 67 0a bd 46 5d f8 04 7b 70 47"

cstool output:

cstool then halts with exception thrown in cstool.c at line 340 "if (ins->detail->groups_count) {"
ins->detail was nullptr

The correct disassembly:

0x080032c2: add r7, sp, #0
0x080032c4: ldr r3, [pc, #0x28]
