A recent change introduced a type cast from a private 64-bit
value to a pointer, which works fine on 64-bit architectures,
but not on 32-bit ones, where it produces a harmless compiler

fs/btrfs/extent_io.c:2193:13: warning: cast to pointer from integer
of different size [-Wint-to-pointer-cast]
This adds an intermediate cast to 'unsigned long', which tells
the compiler to ignore the type mismatch.

Fixes: f612496bca664 ("Btrfs: cleanup the read failure record after
write
or when the inode is freeing")
Already reported, but not merged
I'll take the original cast one for now and we can do the larger
cleanup for the next merge window.
