Btrfs fixes for 7.1-rc4

Hi,

please pull the following fixes, thanks.

- fixup warning when allocating memory for readahead, __GFP_NOWARN was accidentally dropped when setting mapping constraints

- in tracepoint of file sync, fix sleeping in atomic context when handling dentries

- harden initial loading of block group on crafted/fuzzed images, iterate all chunk mapping entries unconditionally

- fix freeing pages of submitted io after checking for errors

- fix incorrect inode size after remount when using fallocate KEEP_SIZE mode (also requires disabled 'no-holes' feature)
