md/raid5: validate payload size before accessing journal metadata

In the Linux kernel, the following vulnerability has been resolved:

md/raid5: validate payload size before accessing journal metadata

r5c_recovery_analyze_meta_block() and
r5l_recovery_verify_data_checksum_for_mb() iterate over payloads in a
journal metadata block using on-disk payload size fields without
validating them against the remaining space in the metadata block.

A corrupted journal contains payload sizes extending beyond the PAGE_SIZE
boundary can cause out-of-bounds reads when accessing payload fields or
computing offsets.

Add bounds validation for each payload type to ensure the full payload
fits within meta_size before processing.
