fs: ext4: change GFP_KERNEL to GFP_NOFS to avoid deadlock
Description

In the Linux kernel, the following vulnerability has been resolved: fs: ext4: change GFP_KERNEL to GFP_NOFS to avoid deadlock The parent function ext4_xattr_inode_lookup_create already uses GFP_NOFS for memory alloction, so the function ext4_xattr_inode_cache_find should use same gfp_flag.
