Fix HDFFV-11101
Description
Added initialization to local structs in the src function
H5MF_settle_raw_data_fsm() and the test function test_bt2_hdr_fd()
to prevent the following error in two different occurrences:
MemorySanitizer: use-of-uninitialized-value
Platforms tested:
Linux/64 (jelly)
Linux/64 (platypus)
