[PATCH v1 49/59] rdma/rdma_rm.c: remove unneeded label in rdma_rm_alloc_pd()

[Daniel Henrique Barboza]

'out' label can be replaced by 'return ret'. Since 'ret' will
be set to -ENOMEM in 'goto' time, we can replace it to
'return -ENOMEM'.

After this change, the 'ret' var is used to store the
result of rdma_backend_create_pd(), see if it's not zero,
then 'ret' is set to -EIO before the jump to out_tbl_dealloc.
-EIO is the only error being thrown by out_tbl_dealloc too.
This means we can go a step further in the code simplification
by also removing the 'ret' variable and making out_tbl_dealloc
return -EIO directly.
