Josh Poimboeuf 1adc93a525 objtool, nvmet: Fix out-of-bounds stack access in nvmet_ctrl_state_show() 
[ Upstream commit 107a23185d ]

The csts_state_names[] array only has six sparse entries, but the
iteration code in nvmet_ctrl_state_show() iterates seven, resulting in a
potential out-of-bounds stack read.  Fix that.

Fixes the following warning with an UBSAN kernel:

  vmlinux.o: warning: objtool: .text.nvmet_ctrl_state_show: unexpected end of section

Fixes: 649fd41420 ("nvmet: add debugfs support")
