Subject: udf: Remove useless check in udf_adinicb_write_begin()
X-Git-Tag: v4.9-rc1~126^2~3

udf: Remove useless check in udf_adinicb_write_begin()

As Al properly points out, len is guaranteed to be smaller than
PAGE_SIZE when we reach udf_adinicb_write_begin() as otherwise we would
have converted the file to the normal format.
