[PATCH BlueZ v1] shared/rap: Fix step payload pointer in parse_step

[Prathibha Madugonde]

From: Prathibha Madugonde <prathibha.madugonde@oss.qualcomm.com>

util_iov_pull advances iov_base before returning the new pointer, so
mode_iov.iov_base was set to the start of the *next* step's data.
Every step was therefore parsed using its successor's bytes.

Switch to util_iov_pull_mem which saves the original base, advances
iov, and returns the pre-advance pointer — correctly pointing to the
current step's payload.
