target/armv7m: fix static analyzer warning

Despite of assert(is_packed) clang static analyser complains on use
of the uninitialized offset variable.

Cross compiling with latest x86_64-w64-mingw32-gcc hits warnings
src/target/armv7m.c: In function ‘armv7m_read_core_reg’:
src/target/armv7m.c:337:54: error: ‘reg32_id’ may be used
uninitialized in this function [-Werror=maybe-uninitialized]

It happens because mingw32 defines assert() without the attribute
"noreturn", whatever NDEBUG is defined or not.

Replace assert(is_packed) by if (is_packed) conditional and call
assert(false) in the else branch.
