Subject: [PATCH] shared/bap: Fix load of misaligned address error

This fixes the "load of misaligned address" error that appears when
parsing PAC caps:

src/shared/bap.c:6497:7: runtime error: load of misaligned address
0x502000063639 for type 'uint16_t', which requires 2 byte alignment

0x502000063639: note: pointer points here
