nvram: fix memory leak
Fix memory leak on nvram_open() and nvram_open_rdonly(). For nvram_open(), the 'fd' should be closed on error, and mmap_area should be unmap when nvram magic can not be found. For nvram_open_rdonly(), the 'file' variable should free before return. Once nvram_find_mtd() return successfully, it will allocate memory to save mtd device string. Signed-off-by: BangLang Huang <banglang.huang@foxmail.com> (cherry picked from commit 1948d8e08c72106a01b359a30217cf92657cc79d)
