[PATCH v2 2/2] nvmet: remove workarounds for gcc bug wrt unnamed fields in initializers

[Niklas Cassel]

Workarounds for gcc issues with initializers and anon unions was first
introduced in commit e44ac588cd61 ("drivers/block/nvme-core.c: fix build
with gcc-4.4.4").

The gcc bug in question has been fixed since gcc 4.6.0:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676

The minimum gcc version for building the kernel has been 4.6.0 since
commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6"),
and has since been updated to gcc 4.8.0 in
commit 5429ef62bcf3 ("compiler/gcc: Raise minimum GCC version for
kernel builds to 4.8").

For that reason, it should now be safe to remove these workarounds
and make the code look like it did before
commit e44ac588cd61 ("drivers/block/nvme-core.c: fix build with gcc-4.4.4")
was introduced.
