shared/mgmt: Fix not processing request queue

From: Luiz Augusto von Dentz <[email protected]>

If the kernel returns an invalid opcode like below the request won't be processed making it unusable:

@ MGMT Command: Read Advertising Features (0x003d) plen 0 {0x0001} [hci0] 14:25:11.096370
@ MGMT Event: Command Status (0x0002) plen 3 {0x0001} [hci0] 14:25:11.096373

      Set Advertising (0x0029)
              Status: Not Supported (0x0c)

In order to fix this attempts to remove the first request pending on the given index:

= bluetoothd: src/advertising.c:read_adv_features_callback() Failed to read advertising features: Not Supported (0x0c)
