ext4: fix potential memory leak in ext4_fc_record_regions()

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

ext4: fix potential memory leak in ext4_fc_record_regions()

As krealloc may return NULL, in this case 'state->fc_regions' may not be
freed by krealloc, but 'state->fc_regions' already set NULL. Then will
lead to 'state->fc_regions' memory leak.
