Li Huafei 6b4b3b8404 ima: Fix the error code for restoring the PCR value
[ Upstream commit 7990ccafaa37dc6d8bb095d4d7cd997e8903fd10 ]

In ima_restore_measurement_list(), hdr[HDR_PCR].data is pointing to a
buffer of type u8, which contains the dumped 32-bit pcr value.
Currently, only the least significant byte is used to restore the pcr
value. We should convert hdr[HDR_PCR].data to a pointer of type u32
before fetching the value to restore the correct pcr value.

Fixes: 47fdee60b4 ("ima: use ima_parse_buf() to parse measurements headers")
