From: Jianglei Nie <[email protected]> elfcorehdr_alloc() allocates a memory chunk for elfcorehdr_addr with kzalloc(). If is_vmcore_usable() returns false, elfcorehdr_addr is a predefined value. If parse_crash_elf_headers() gets some error and returns a negetive value, the elfcorehdr_addr should be released with elfcorehdr_free().
Fix it by calling elfcorehdr_free() when parse_crash_elf_headers() fails.
