ext4: remove redundant max inline_size check in ext4_da_write_inline_data_begin()

ext4_prepare_inline_data() already checks for ext4_get_max_inline_size()
and returns -ENOSPC. So there is no need to check it twice within
ext4_da_write_inline_data_begin(). This patch removes the extra check.

It also makes it more clean.

No functionality change in this patch.
