RDMA/bnxt_re: Fix a potential memory leak in destroy_gsi_sqp

The current error handling path in bnxt_re_destroy_gsi_sqp() could lead
to a resource leak. When bnxt_qplib_destroy_qp() fails, the function
jumps to the 'fail' label and returns immediately, skipping the call
to bnxt_qplib_free_qp_res().

Continue the resource teardown even if bnxt_qplib_destroy_qp() fails,
which aligns with the driver's general error handling strategy and
prevents the potential leak.
