[Skiboot] [PATCH 3/3] astbmc: Fix uninitialised variable warning

[Joel Stanley]

platforms/astbmc/pnor.c:43:6: error: variable 'pnor_chip' is used uninitialized whenever 'if' condition is true
      [-Werror,-Wsometimes-uninitialized]
        if (rc) {
            ^~
platforms/astbmc/pnor.c:58:6: note: uninitialized use occurs here
        if (pnor_chip)
            ^~~~~~~~~
platforms/astbmc/pnor.c:43:2: note: remove the 'if' if its condition is always false
        if (rc) {
        ^~~~~~~~~
platforms/astbmc/pnor.c:30:30: note: initialize the variable 'pnor_chip' to silence this warning
        struct flash_chip *pnor_chip;
                                    ^
                                     = NULL
