wifi: rtw89: debug: Fix memory leak in __print_txpwr_map()

Browse source

In __print_txpwr_map(), memory is allocated to bufp via vzalloc().
If max_valid_addr is 0, the function returns -EOPNOTSUPP immediately
without freeing bufp, leading to a memory leak.

Since the validation of max_valid_addr does not depend on the allocated
memory, fix this by moving the vzalloc() call after the check.

Compile tested only. Issue found using a prototype static analysis tool
and code review.
