[next,0/2] btrfs: Fix build warnings for arm

Message

Hello Wenruo and Dave,

This mini-series fixes two build warnings found while cross-compiling for arm,
using openSUSE's cross-arm-binutils and cross-arm-none-gcc9 packages.

Replacing BUG_ON() with btrfs_crit() error handling is noble work, but please
be careful not to hardcode format specifiers for x86_64's size_t.

https://www.kernel.org/doc/Documentation/printk-formats.txt

In one case it could've been noticed during review, in another it was hidden
through a macro and would've only been found through compile-testing.
Probably a 32-bit i386 build would do; otherwise ARCH=arm multi_v7_defconfig
plus CONFIG_BTRFS_FS should reproduce.

It's around for maybe three weeks, so I wonder why kbuild bot didn't catch it.

Cheers,
Andreas
