Qilin Tan 9214a5484e f2fs: fix iostat lock protection 
commit 144f1cd40b upstream.

Made iostat lock irq safe to avoid potentinal deadlock.

Deadlock scenario:
f2fs_attr_store
  -> f2fs_sbi_store
  -> _sbi_store
  -> spin_lock(sbi->iostat_lock)
    <interrupt request>
    -> scsi_end_request
    -> bio_endio
    -> f2fs_dio_read_end_io
    -> f2fs_update_iostat
    -> spin_lock_irqsave(sbi->iostat_lock)  ===> Dead lock here

Fixes: 61803e9843 ("f2fs: fix iostat related lock protection")
Fixes: a1e09b03e6 ("f2fs: use iomap for direct I/O")
