Ye Bin 9b5eb368a8 ext4: fix potential memory leak in ext4_fc_record_modified_inode() ...

commit 9305721a309fa1bd7c194e0d4a2335bf3b29dca4 upstream.

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