ext4: fix unaligned memory access in ext4_fc_reserve_space()
As is done elsewhere in the file, build the struct ext4_fc_tl on the
stack and memcpy() it into the buffer, rather than directly writing it
to a potentially-unaligned location in the buffer.
Fixes: aa75f4d3daae ("ext4: main fast-commit commit path")
