Jan Kara bc9d8a3ba0 udf: Fix deadlock in udf_release_file() ...

commit a0391a3ae9 upstream.

udf_release_file() can be called from munmap() path with mmap_sem held.  Thus
we cannot take i_mutex there because that ranks above mmap_sem. Luckily,
i_mutex is not needed in udf_release_file() anymore since protection by
i_data_sem is enough to protect from races with write and truncate.
