ext4: remove a BUG_ON in ext4_mb_release_group_pa()

CVE-2023-53450

Description

In the Linux kernel, the following vulnerability has been resolved:

ext4: remove a BUG_ON in ext4_mb_release_group_pa()

If a malicious fuzzer overwrites the ext4 superblock while it is mounted such that the s_first_data_block is set to a very large number, the calculation of the block group can underflow, and trigger a BUG_ON check. Change this to be an ext4_warning so that we don't crash the kernel.
