ext4: fix overflow caused by missing cast in ext4_resize_fs() [ Upstream commit aec51758ce10a9c847a62a48a168f8c804c6e053 ] On a 32-bit platform, the value of n_blcoks_count may be wrong during the file system is resized to size larger than 2^32 blocks. This may caused the superblock being corrupted with zero blocks count.
