cxgb4/chcr: avoid -Wreturn-local-addr warning
gcc-10 warns about functions that return a pointer to a stack variable. In chcr_write_cpl_set_tcb_ulp(), this does not actually happen, but it's too hard to see for the compiler: drivers/crypto/chelsio/chcr_ktls.c: In function 'chcr_write_cpl_set_tcb_ulp.constprop': drivers/crypto/chelsio/chcr_ktls.c:760:9: error: function may return address of local variable [-Werror=return-local-addr] 760 | return pos; | ^~~ drivers/crypto/chelsio/chcr_ktls.c:712:5: note: declared here 712 | u8 buf[48] = {0}; | ^~~ Split the middle part of the function out into a helper to make it easier to understand by both humans and compilers, which avoids the warning.
