[PATCH for-next v4 1/4] RDMA/rxe: Replace exists by rxe in rxe.c

[Bob Pearson <rpearsonhpe@gmail.com>]

'exists' looks like a boolean. This patch replaces it by the
normal name used for the rxe device, 'rxe', which should be a
little less confusing. The second rxe_dbg() message is
incorrect since rxe is known to be NULL and this will cause a
seg fault if this message were ever sent. Replace it by pr_debug
for the moment.

Fixes: c6aba5ea0055 ("RDMA/rxe: Replace pr_xxx by rxe_dbg_xxx in rxe.c")
