xprtrdma: Fix uninitialized variable
net/sunrpc/xprtrdma/frwr_ops.c:151:32: warning: variable 'rc' is uninitialized when used here [-Wuninitialized]
trace_xprtrdma_frwr_alloc(mr, rc);
^~
net/sunrpc/xprtrdma/frwr_ops.c:127:8: note: initialize the variable 'rc' to silence this warning
int rc;
^
= 0
1 warning generated.
The tracepoint is intended to record the error returned from
ib_alloc_mr(). In the current code there is no other purpose for
@rc, so simply replace it.
