wifi: iwlwifi: mld: Ensure wiphy lock is held during debugfs read operations
The WIPHY_DEBUGFS_READ_WRITE_FILE_OPS_MLD macro is intended to call
read/write handlers with the wiphy lock held. However, the current
implementation uses the MLD_DEBUGFS_READ_WRAPPER macro, which does
not hold the wiphy lock during read operations. This fix updates
the WIPHY_DEBUGFS_READ_WRITE_FILE_OPS_MLD macro to use the
WIPHY_DEBUGFS_READ_WRAPPER_MLD macro instead, ensuring that the
wiphy lock is held during both read and write operations.
